I had a small issue with one of our thrones (pic below), so ended up buying a new one. Turns out Denver Water (and quite a few providers that use it - see the list) is giving $125 each for up to 3 new water-efficient toilets in your house. The Kohler model I picked up was $128, and with this I am getting a couple more to update our other bathroom and finish the basement one, basically for $9 for the house. If you buy one under $125 you still get the full rebate (meaning you make money renovating your bathroom).
Toilets aren't too exciting, but if you are planning on getting a new one (or three) in your house, you have until the end of December to cash in on free money which is pretty exciting.

There are also other rebates going on, but this is by far the best one as far as potentially getting free stuff.
