Well that depends on where you go. If you go to a petland that does carry baby aro's, they were asking for $20 or more.
I go to one place only, and if you're in manhattan you probably can guess where.
Prices are always cheaper at these local LFS than going to a petland or petco. One guy use to have a shop on Hester st, but he packed up and left. The other place is by the Willy B, they have decent prices and a good selection most of the time. Besides those guys that work there are really into the hobby themselves and know a lot about aro's.
Hmmm...as a matter of fact I should drop by there, only bad thing is parking is a pain in the arse in that area.
