I would buy one from a breeder as opposed to the pet store, less risk of it being unhealthy. And as I have not done too much research on prices of lavenders, the prices can vary on corns depending on what hets. they have. A basic lavendar with no hets is going to cost you less than a lavender with hets for other morphs. I would just compare that with some of the prices of corn breeders online. I would give you links to some of them but the last time I looked at them I just googled them and don't know any of the sites that I looked at offhand. I hope this helps you some.
