There are several reptile rescues that will take in reptiles you can not keep anymore. Searching for them on Google will help find one and I know one member on this site has one set up as well.
It depends on where you live. I know there is a nice mom and pop pet store around the corner from me that will take in rescues and other reptiles that people can not afford anymore.
Depending on where you live, or whether you're equipped to ship them, I may be able to help.
We just opened our gecko surrender facility, and we're equipped for just this sort of thing. Right now we're located between Iowa and Illinois in the US.
If you are too far away from us and you can't ship, there are always other rescues but they're sometimes hard to find. The local vet might know where you can give them. Or maybe a member here lives close enough to you and is willing to take them. I wouldn't give them to a pet store or put an ad on Craigslist or anything until you know for sure that you're out of options.
