Honestly, all the person asked for was if their snake is going to be okay, they don't need all the pet store backlash. Posting 'oh it's not a rescue' everytime you see the word PetSmart isn't doing anything. To me if the person is giving the animal better living conditions, I label it as a rescue, no matter if money was involved. You see people 'rescue' dogs from shelters everyday and chances are they paid an adoption fee. Does that mean it isn't a rescue? No.
Bashing people from getting their snake from PetSmart isn't doing a thing, the animal is already purchased.
Good luck with your BP though, would love to see pics^^
