Little confused???
 

My Retic arrived today but was packed with no heat!!! He was really cold .. I put him in a heat tub immediately.. not sure why their wasn't any heat provided? This is a big name breeder as well....

Temps are in upper 40's

I would start by documenting (emailing) this fact with the seller/sender... just in case.
Big name breeders can have small name employees packaging things for them.

Way ahead of you.. and the breeder contacted me within 5 minutes after I emailed him.. he stated it was warm on his end an throughout the travel stops as well... I have him in a heated tub 92 hot spot an 80 ambient temperature with a hide box in a dark quite room.. I'll leave him be untill this evening then check up on him...

This time of year temperatures can vary pretty widely for a shipped critter depending on where it originates, the FedEx hub it passes through, and the destination. While too little heat can make the critter uncomfortable, too much can cause irreversible neurological damage or death.

Retics are normally pretty touch and can stand being cool for a few hours with no ill effects. Obviously your new arrival should be quarantined for at least 90 days, as you would do with any new reptile, but I wouldn't be surprised if it were ok.
