There is both a $5 Filtrete rebate and a $10 Filtrete coupon (try 77477) for the Filtrate systems at Walmart. These are really nice and this would be a good way to get one for less. Plus there is also a $5 Filtrete Advanced water kit coupon as well.
This could also be a gift to someone for Christmas. Is our family the only weird people who give gifts like this?
* I called 3M the manufacturer just to check for you and they consider the coupon an offer, so you need to choose one or the other! 🙂
