I was over charged for an item and didn't realize it until I got home. How do I get a refund?

Call the store. Phone number should be on the receipt. They will tell you to bring the receipt in.

Return the item to the store with your receipt. If you are not satisfied with the results call 1 800 WALMART customer service. They'll take care of it. But you must allow the store to make amends first.

I would take the item and receipt to customer service
