Your favorite Dollar Store or Free stuff

I thought I'd start a thread on your favorite finds. Some of my Dollar Store favorites are a thin-bladed metal kitchen spoon for scooping poop, a little ceramic dip dish that says "good friends, good food" which I use as a food dish, a fleece that I cut up for mats under the hideys along with an old wash cloth beneath, some neat clips for clipping fleece to the grid to make tents in the corner of the cage. Freebies: Oatmeal boxes taped together to make tunnels, same with tissue boxes, enlarging the opening and cutting another on the end, and the cat litter jug "trays" I described in a tips thread here.

I'd love to hear from other members ! What are a few of your favorite things? (and who has that song running through their mind now??)
