When my sister-in-law told me there was a resale kids shop in Las Vegas, I organized a bunch of stuff and hauled it in the next day. I think that they give about 10-15% of their sale price. Here is an example: I sold them my son's $50 Lucky Brand Jeans. They'll sell them for $12 or so which means I'll get $1.20 for those perfect condition jeans.
I went in there with tons of jeans, jackets, shirts (mostly all of which were baby gap), a stroller, rainforest play gym, and a luxe boppy. This was easily $600 worth of stuff and when I saw that they bought everything, I expected quite a bit of money. Intead, I got $41.
I later went back there to sell small toys because toys probably wouldn't sell for much at a yardsale or on eBay anyway, but I saw the $60 play gym I sold them selling for $25 which means I got $2.50 for it. There was also the same playgym there missing various pieces and filthy selling for $20 which means I only got paid $0.50 more. I will definitely be selling my stuff on eBay and Craigslist and bringing in the rejects to this store.
Shopping here on the other hand is a bargain. Some of their stuff is still new including robeez shoes ($40 at Daggermans) selling for $10. I will probably come here to buy a new pair of robeez and maybe some toys for the kiddos.
