So fresh so clean - Silicone replacement brush head:  $1 @ Winners (RSP:  $4.99 - $7)

The same one I bought a while back for twice the price.  It seems like I only find them when they're on clearance!  I've never seen a cache of them at full price anywhere.

Anyway, I picked this one up for my mom.  They never need to be replaced so I don't see myself picking up more.
