Save money on groceries and household essentials with these easy to use rewards programs

I'm not using these rewards to cut our grocery budget drastically. Instead I'm using them to tuck away a little bit here and there for buying items that are already on my list so we have some extra cash for fun splurges or Christmas and birthday gifts. Again, it's not going to put mega bucks in your pocket, but if you are already shopping, what does it hurt to spend a few minutes uploading your receipt to a few places to earn some pocket change?
