I second the Het guarantee as being a more value added one.
On the discussion of guaranteeing something in your TOS a lawyer will tell you it's complicated. Really guaranteeing live arrival and genetics is all people "can" do since they can't guarantee the enviornment after the animal arrives.....they can try to guarantee the animal after arrival but there are alot of variables outside of their care. They are basically guranteeing the customer's treatment and care of the animal by the owner....something they have no control over.
Also in writing up TOSs, I'd suggest putting something in there about DOAs and verifying the animals. I read a series of posts on fauna about claiming DOAs and sending back crappy pics or saying they threw the animal out. Sure enough the animal was actually still alive and it was a scam. Something to watch out for and keep in your TOS to avoid such a situation. (e.g. no refunds without a returned corpse etc.)
Somethings I struggle with too
Hope that helps!
