I found gently used CD's at a local store!
I wandered into this new-ish baby boutique yesterday and found a (very) small collection of gently used CD's for sale! I'm not shopping for diapers anymore, but it was cool to see. They mostly had KL0s, fuzzibunz, and imse vimse covers.
considering that this is not exactly a "greenie" area, that was very exciting!
I can't remember the name of the store... Green something. It's in the Eagle Rock area of los angeles.
