I buy about 95% of my food there also. The best part is my office falls is in a UPS 1-day service area, so it gets here overnight and the shipping is free. The flakes in those bags are really big and the bags are a little clumsy to work with; even though they are zip-tops. I fill a smaller glass jar with about what I'll use in a week or so and put the rest in the fridge. I have 23 tanks to feed and even I have to keep the notion that the stuff can go stale in the back of my head.
