EDIT: This offer is no longer available.
Remember the free General Mills Que Rica Vida program I wrote about earlier? It's back again and is a pretty good freebie source for anybody who speaks Spanish or has access to Google Translate (edit: or use Adam's handy chart from two years ago). Last week I got a box from them with a Nature Valley Oats ‘n Honey bar, some Cinnamon Toast Crunch, a large Bisquick baking mix pack, and $3 in coupons.
Every package seems to have different freebies, so it's like a mystery as to what you'll get. Just imagine you're on a modern day version of Let's Make A Deal and about to find out what you won. In fact, do that with every aspect of your life and you'll find that many everyday activities are enhanced.
