Yep, it’s another Walmart receipt checker story! At the end of it, the OP asks, “What should I do?” And I sigh. I really don’t know. Don’t shop at Walmart anymore? Try to encourage your friends to not give their business to any company that acts in such a hostile way to honest, albeit uncooperative, customers? Spend a ton of money on a lawsuit that Walmart will use its very deep pockets to fight?
