Well damn, I just read this entire Costco a-go-go thread this morning. Here I am in the middle of Mexico--and there is a huge Costco only an hour away! I have to go there on Tuesday, just a little late for the go-go. Here's what I usually buy there: TP, paper towels, paper napkins, evaporated milk, wines, liquor. I've not bought meats or fish, but others swear by them. The standard array of products available in the USA is available here, for the most part, with some country-specific differences: all the books are in Spanish, the dry and canned goods are heavy on the things we use here: rice, beans, fideos, chiles en escabeche, etc. We get delicious pitted green olives stuffed with anchovies; I'm not an anchovy lover, but I love these. Here's a point to ponder: Wal-Mart is the largest private employer in Mexico. Scary, huh?
