I'm loving RecycleBank! Register and receive 100 points just for doing that. Once you register you will need to log out and then log back in and you will see your 100 points. I did this the other night and I redeemed 90 of my points for (2) $2 off Cascadian Farms products (this is awesome because my husband LOVES their granola and applying these coupons to a sale price will get me some granola at a great price.) AND (1) FREE bottle of 7th Generation Dish Liquid (LOVE the Lavendar scent). These will be mailed to me and I cannot wait to get them!
