Quality and lineage play a bit of a roll in chameleon pricing...I would also suggest holding onto your babies as long as you can.
One of the advantages of holding onto your babies until they hit 3-4 months is you get to see the colors begin to come in, and if you have some real stunners you can raise the price on them.
Most people are more than happy to pay a little extra if they can see the potential, especially if you sell to other breeders who are always looking for new breeding stock.
