It is a normal, but I'll post something more then "it's a normal."

I actually had the pleasure of seeing a few yb babies a few weeks ago, they are subtle but very cool looking. Not all have yellowbellies but they do have flames and the markings... I have a normal female that looks similar to the one you have put up and she's a normal.

Is it possible that when the deliveries were being made, he dropped the wrong snake bag off and pet shop owner didn't look in the bag? Or maybe this Amir person mis labeled the bag? Something along those lines?

Maybe call the pet shop and say "you sold me a normal, I have posted numerous pictures of this animal and everyone is saying it's a normal. Something could have possibly happened and maybe you just sold me the wrong snake"

He's probably trust Amir and going by what he said. I think if this Amir person saw the snake, he would probably say he dropped the wrong bag off. This is taking into consideration what was said earlier about delivering numerous ball pythons to many pet stores.

That's my input.
Thanks,

Mike
