how much grocery shopping do you do for your household?

I would say that I do about a quarter of the households grocery shopping. I shop for personal care items and such that are needed around the house. If I want to try out a few recipes for the house, than I need to pick up some slack and go grocery shopping. I know that my parents appreciate it when I go grocery (food) shopping every so often, helps them out a little bit. My mom does most of it, but like I said, I will pitch in now and again. I will go maybe once or twice a month and make those tiny little restocking trips sometimes once a week.
