Shopping Rules:
#1 Never go shopping when you are tired and hungry (especially late in the afternoon, when you have skipped lunch), and #2 Don't take you kids shopping with you. 

Please follow these rules.  Otherwise, you may come home, open your grocery bags, and realize that they are full of random things that looked good to you or your kids at the store. (Do I eat eggplant?)  You may also find a key ingredient for dinner is missing completely.
