Here are a few tips on how to shop for groceries:
1) Make sure that total food purchases do not exceed more than 25% of the total weight or 30% of the total cost of your shopping trip.
2) When shopping in Austin where Real Ale's Fireman's 4 is flying off the shelves, do not satisfy yourself with only one 6-pack when there is a whole case to be had. Even if Fireman's 4 is not your favorite Real Ale, get a case so that you can impress your friends and other people who were not able to buy any because you were so selfish

3) Always buy plenty of something cheap for your cheap/unappreciative friends when they come over. For example, the Session is on sale for $10/12pack. The Allagash is for yourself
