That video sums up everything you need to know about Walmart. And America. And global economics, really.
I agree with this. Sam's Club is soooo much better than Costco!I like Sam's Club better, not because it's objectively better but I'm used to it and it has particular things I like that Costco doesn't xD It's from the same company as Wal-Mart though haha.
There is one thing I will say about Walmart - they provide tons of inadvertent entertainment. If you like people watching that is.
