I plan to start breeding in the next three years (girls gotta grow) and I often think about guarantees, disclaimers, agreements, etc. For hets I decided to offer two year guarantee and if they do not proove out then I'll take back the snake in exchange for store credit or a similar animal of the buyer's choice. In order for the guarantee to apply they must have evidence of locks, mom on eggs, slugs, pipping, etc. If I have any doubt if a snake is 100% het then it is marketed as a normal only.

Of course I reserve the right to challenge the buyer's claim if I smell fishy business!
