CVS Clearance - Hair brushes, hand mirrors, hair clips, hair bands, shower caps, and more at 50% to 75% off (YMMV)
I've attached some pics, although there is a LOT more that I didn't photograph because I felt weird taking pictures in the store.
The main brands on clearance were scünci and Conair.
I got a few hair bands and a set of foam rollers for about $10, when the foam rollers on their own are usually around $15!
I'm not sure if other stores are doing this, so it's YMMV. I think it would be strange for a single store to discount so many products, though. Let me know if it works for you! This particular store is in SoCal.
