I shop at costco the way I imagine women shop for clothes. I cruiese pretty much every isle and look at things not only do I not need, but probably no one needs. I hit the non-food items first then wander on over to the food area and just let the magic and wonder of getting random shit in bulk wash over me.

John's lunches are pretty much entirely decided by what costco has available. And whatever our primary dinner meats are going to be is also based on what I can find at a price I'm willing to pay.

Occassionally you find amazing things like a 1.5L bottle of cheap sparkling wine for $6 so that I can make mimosas.

Costco is like an REI for food, or a candy store for kids.
