I love unpacking my car with the grocery bags that I can reuse and not feel sick about having more plastic bags than I'll ever need or paper bags to store. These bags are from Trader Joe's and Sunflower Market (it used to be in Indianapolis, but isn't there anymore). I know some places you can buy reusable grocery shopping bags for $.99. Otherwise, reuse old plastic or paper grocery bags or use any canvas type bag you have in your home already. Happy shopping :)!
