a real breeder, as in store/business, i would say 48 hours for sure for any reason, 2 weeks due to medical (with proof of course) reasons..... should have FULL refund or credit.
private sales, a day, maybe two..... if anything. i know if i sell something the money is already spent! some people might be able to refund or get another animal but usually not if it's just the one snake they were selling. some who do alot of private sales should do the refund thing mainly for reputation purposes.
i know most stores don't though, or give a crappy credit, if any credit, when they know the animals won't make it.
grrrrr @ them.
