You check places like Dubi Deli, BuyDubiaroaches.com, Kimbrell's Cold Blood? Those are the 3 that come to mind. I guess it really boils down to how fast you want to move them and how much you feel they are worth to you. Like I said, I just sell mine for $15 per 100 any size and $1 for females on my local Craigslist. Even at that price I sometimes get undercut by other people doing $10 for 100. Again I guess it boils down do you want to get rid of them for something or keep feeding your surplus which in my case got expensive as they just destroyed anything I put in the bin.
