As you become an extreme couponer, it's important to remember to only purchase items you'll use. Don't buy 15 cans of tuna because you can get a great if you don't like tuna and will never eat what you bought (unless you want to donate the cans to a good cause -- then go ahead). Use your couponing skills for items you need. Besides, if you buy a plethora of products you won't use, you haven't actually saved any money. You've just wasted precious funds on things you don't need, so be a wise shopper and look for sweet deals on stuff that you'll actually enjoy.
