Alright, hit the 6-month mark on Walmart US. Doing about $5-7k a week—not enough to quit my day job, but enough to learn some painful (and occasionally profitable) lessons the hard way. I run my own warehouse and also sell on Amazon, so this is straight from the trenches of a multi-channel grunt.

Mistake #1: I Made the FBA Mistake. Don't.

Thought I was being smart using my FBA stock to fulfill Walmart orders. Account got restricted in 72 hours. The policy is no joke, and Walmart's tracking deadline (like, 2 PM ET the next business day?) is impossible for FBA to hit. Just use a 3PL or your own fulfillment. This isn't a gray area—it's a cliff.

Mistake #2: The Ghost Return Address Trap

Set up everything, forgot about returns. Big mistake. When a customer returns something to a Walmart store, they ship it somewhere. If that "somewhere" isn't a valid U.S. return address you've provided, you just donated your product to a Walmart shipping hub. Get a 3PL or virtual address for returns. Now.

Weird Trick #1: Ads Aren't the God (For Once)

Coming from Amazon, I braced for PPC bloodshed. Shockingly, some of my listings just… sell organically. No ads. Lower ad competition means you can sometimes rank without burning cash. But this is category-dependent—my home goods do this; your mileage may vary.

Weird Trick #2: The Margin Mirage is Real (Sometimes)

Because there aren't as many sellers racing to the bottom, I've held prices $5–10 higher on Walmart than on Amazon for the same item. Fewer buyers, but fatter margins. It's a different kind of math.

Questions for the veterans:

  • Has WFS been a game-changer for you, or just another fee?

  • Is anyone else's category showing real growth, or is it just mine?

  • What's your secret sauce for not getting killed by returns?
