Does anyone here do rebates? I've managed to do rather well engaging in this. Saving upc seals, box tops, etc., has brought me coupons for free products, dollars off, and even rebate checks or Visa gift cards. I'm not totally into as my sister is, but she has more time to devote to it than I. I have went grocery shopping with her and seen her get $100.00 worth of groceries for $25.00 or less, using coupons, rebate money, gift cards, etc. It can be time consuming though. Just curious if anyone else does this?? Any tips?
