check out the good advice in this recent thread: https://ball-pythons.net/forums/show...10#post2564110
the seller may be new to MorphMarket, but may have feedback and history on FaunaClassifieds or even here on BP.net
also u can always put in a dispute via Paypal if u get ripped off as long as u don't send the payment as a gift (which can be a red flag in itself).
Edit: also f/u with the seller asap esp. if there's something wrong. don't wait, u gotta push for a swift resolution. some peeps even take pix or vids of their unboxing just in case.
