I give a 30 day sex guarantee. at the shows, I always recommend having someone check it again before they leave. the guarantee is so someone don't come to me a year or 2 later. I also check any snake I receive within a reasonable amount of time, and if someone didn't get it check within the 30 days. but shortly after, I would still honor the guarantee. I'm not trying to get out of a mistake, but just having it done in a reasonable amount of time.
