A flipper is someone who buys snakes from one party with the intention of reselling them. It's often used as a pejorative term.
Personally I find the current negative attitude towards 'flippers' to be puzzling. Every single pet store since the beginning of pet stores is a flipper. There isn't a pet store anywhere that I've ever heard of that breeds all of the animals that they sell. Petco is a flipper, Petsmart is a flipper, that Mom and Pop pet store down on the corner that has been in business for 50 years is a flipper.
I'd be willing to bet that most of the people that are currently in this hobby first became exposed to it because they saw a snake for sale in a pet store.
The REAL issue here is NOT whether or not LLLReptile is a flipper, they're a pet store, of course they are. The real question here is whether or not they have a pattern of reselling snakes that may be sick. And THAT is the issue that needs to be addressed. Pointing fingers at them and shouting 'FLIPPER' like it's some kind of swear word does nobody any good and just clouds the real issue. At least in my opinion.
