A repair bill is rarely the reason to buy the Grand Expedition Yak. The real appeal is being able to finish a transmog run, sell the unwanted loot, and try on the pieces you kept without returning to a capital. For a collector who regularly runs old content, that convenience can matter more than another elaborate flying animation.

The purchase itself is refreshingly straightforward. Uncle Bigpocket sells the yak in Kun-Lai Summit for 120,000 gold. There is no reputation ladder to climb, boss to camp, or weekly achievement standing between you and the reins.

Quick Answer

Buy Reins of the Grand Expedition Yak from Uncle Bigpocket at the Grummle Bazaar in Kun-Lai Summit, Pandaria, around 65.4, 61.8. Bring 120,000 gold on the purchasing character, buy the reins, and use them to learn the mount. Both factions can make the purchase.

This is an obtainable gold vendor mount with two useful NPC passengers: Cousin Slowhands provides vendor and repair services, while Mystic Birdhat provides transmogrification. It is a ground mount, so its portable services are available where you can actually summon and remain on it.

Mount Overview

The yak comes from Mists of Pandaria and looks built for an expedition rather than a parade. Its heavy frame, broad horns, travel gear, and passenger platforms make it feel like a small moving outpost. The grummles riding alongside you are part of its identity, not decoration added to a normal riding yak.

It also occupies an unusual place in a collection. Many mounts are acquired for their appearance and then rarely leave the journal. This one can become a practical shortcut even when your favorite travel mount is something else entirely. You summon it for a specific service, finish the job, and get back to your regular ride.

Do not confuse it with the Blonde Riding Yak or Grey Riding Yak sold nearby. Those are separate collection entries and cheaper riding mounts. Buying one of them does not give you the expedition yak’s passengers or services.

How to Get the Grand Expedition Yak

1. Put the purchase gold on your buying character

You need 120,000 gold available to the character talking to Uncle Bigpocket. Gold held elsewhere in your account is useful only after you make it accessible to that character. Sorting this out before traveling saves a particularly avoidable return trip.

Budget the full current vendor price. Old comments mentioning a 108,000-gold purchase refer to the former guild Bartering discount. They are not a reason to join a guild, change race, or delay the trip while searching for a reputation discount.

2. Travel to Kun-Lai Summit in Pandaria

Use an available route into Pandaria, then travel to Kun-Lai Summit. A character with an established route to the Vale of Eternal Blossoms can continue north into the zone. If you are already questing in Pandaria, there is no need to return to your faction capital just to begin this purchase.

The destination is the Grummle Bazaar, not a stable in a major city. Flying makes the approach convenient, but flying is a travel choice here rather than a separate unlock required by Uncle Bigpocket’s shop.

3. Find Uncle Bigpocket at the Grummle Bazaar

Look around 65.4, 61.8 in Kun-Lai Summit for Uncle Bigpocket, whose title is Used Yak Salesgrummle. Coordinates can vary slightly between map pins because of where a marker is placed; you are looking for the merchant in the bazaar, not a hidden cave entrance.

If using a coordinate addon, select Kun-Lai Summit before entering the waypoint. A correct pair of numbers on the wrong zone map will not take you to the seller.

4. Buy the correct reins and learn them

Open the merchant window and select Reins of the Grand Expedition Yak. Uncle Bigpocket also sells ordinary riding yaks, so read the full item name before paying. The expedition version is the 120,000-gold purchase.

Use the purchased reins from your bags, then search for Grand Expedition Yak in the Mount Journal. Buying the item and learning the mount are separate actions. Once learned, it becomes available through your account’s collection for eligible characters.

Location

• Continent: Pandaria.
• Zone: Kun-Lai Summit.
• Local destination: Grummle Bazaar.
• Vendor: Uncle Bigpocket, Used Yak Salesgrummle.
• Approximate position: 65.4, 61.8.

The merchant is out in the zone. You are not looking for a dungeon entrance, a raid difficulty setting, or a special event version of the bazaar. A missing raid reset or inactive Timewalking week has no bearing on this purchase.

Requirements

The meaningful acquisition requirements are the gold, access to the vendor, and the ability to learn and use a normal ground mount. There is no Grand Expedition Yak reputation faction, and you do not need to finish the Kun-Lai storyline first.

• Have 120,000 gold on the buying character.
• Reach Uncle Bigpocket in Kun-Lai Summit.
• Purchase and use the correct reins.
• Use the mount on an eligible character in a location that permits mounting.

Neither faction has an exclusive version to buy. This also is not a profession mount: you do not need Engineering, a crafted saddle, or a recipe. Its original expansion is useful for finding the seller, not a reason to look for a separate paid mount bundle.

Using the Passengers Properly

Cousin Slowhands is the vendor and repair passenger. Summon the yak, interact with him, repair damaged equipment, and sell the loot you no longer want. Repairing still costs gold; owning the mount gives you access to the service rather than free repairs.

Mystic Birdhat handles transmogrification. The passenger originally associated with reforging in older descriptions was changed when that system was removed. In present-day Retail, this is a transmog convenience mount, not a way to reforge equipment statistics.

Remember the mounting restriction when planning around either service. An outdoor area of a dungeon may allow the yak, while an indoor corridor may not. “Portable” does not mean every room allows you to summon it, and it does not let you bypass combat restrictions.

You can dismiss the NPC passengers to make room for player passengers. That is useful for giving someone a lift, but you will not have the dismissed NPC’s service available in that seat at the same time. Resummoning restores the normal arrangement.

Efficient Acquisition and Everyday Use

There is no drop chance to improve here. The efficient route is to choose a character that already has the money and a convenient Pandaria travel option, make one trip, and learn the reins immediately. Running extra characters to the bazaar does not make the mount cheaper or unlock additional account copies.

If you are also collecting ordinary yaks, decide before leaving whether to buy the Blonde Riding Yak and Grey Riding Yak from the same merchant. They are independent purchases. Their lower prices are not installment payments toward the expedition version.

Once the mount is learned, placing it on a convenient action bar or favorites list is more useful than trying to incorporate it into every journey. It is particularly handy after legacy raid clears, while comparing newly learned appearances, and during outdoor sessions when bags fill with vendor loot.

Judge the purchase against how often you actually need the services. A collector running several old instances each week may use it constantly. Someone who rarely changes appearances and already has reliable repair access may prefer to spend the gold on several collection entries first.

Is This Mount Still Obtainable?

Yes. Its acquisition remains the direct purchase from Uncle Bigpocket. It is not tied to a seasonal achievement, a limited shop sale, or the original Mists of Pandaria launch period.

There is no weekly purchase lottery to wait out. If you have the gold and can reach the merchant, you can buy it. Old discussions about a discontinued discount or the former reforging passenger do not mean the mount itself was removed.

Is It Worth Buying?

For transmog collectors, the strongest argument is repeated use. A rare drop gives you a new appearance to ride; this purchase helps with the routine surrounding many other collection sessions. The benefit is convenience each time you summon it rather than prestige from a difficult acquisition.

Its price still deserves consideration. Buying it does not improve your mount drop chances, award extra raid attempts, or remove repair and transmog charges. If those services are already easy to reach during your normal play, the practical gain may be smaller than its reputation suggests.

My collector verdict: prioritize it when portable transmog and repairs solve a regular inconvenience. Buy an ordinary yak instead if you mainly want the silhouette and have little interest in the passengers.

Collection Value

The yak’s long-term appeal comes from having an obvious job in your collection. It does not need to compete with your newest flying mount or match every armor set to remain useful. Keeping a practical mount alongside your favorite cosmetic rides makes a large collection feel more purposeful.

It also suits a quieter Pandaria look: travel clothes, expedition gear, subdued leather, or a character who seems more interested in the next mountain pass than a royal procession. The loaded platforms supply plenty of visual detail without requiring a glowing weapon to complete the scene.

Similar Mounts

• Blonde Riding Yak: the inexpensive option from the same vendor for collectors who want a yak without paying for utility.
• Grey Riding Yak: another separate ordinary yak color, useful if your priority is completing the family.
• Traveler’s Tundra Mammoth: a practical alternative to investigate when your main concern is vendor and repair access.
• Mighty Caravan Brutosaur: another large utility mount, but its auction-related services and acquisition should be evaluated separately rather than treated as a direct substitute.
