Has anyone done this & what is the usual procedure? I am only wanting to know about the contractual side, so for example, do you offer a 2nd straw free if not in whelp 1st time, or if they get in whelp 1st time is there an agreement as to what happens to the 2nd straw etc? Anyone any experience.

I sent 9 straws to the States for one mating, on the advice of our AI person.  Only half were used, and the rest are in storage over there.   

The contract was fairly comprehensive - I'll dig it out, and send it to you
