Costco vs. Walmart

I've only been to a Costco a couple of times ever, as we only had Sam's Club (yes, the Waltons own it...). I love bulk. But here's why Costco is superior to Walmart. As if you needed more reasons than my cute $11 Levis or free samples. Oh and the fact that there are Costcos in Japan, but only secret Walmarts here. Evil bastards.
