The chances are you won't be allowed to put the cards in the store in the first place. My local rescue had to rephrase their advertisement because wording suggested they might have animals for adoption (which, of course, people might be interested in over P@H's sale stock).

I really think you should do yourself a favour and stay out of there altogether. There is no "credit" to give them at all. Is there a particular reason you can't get excel from your vet or online? I literally have to walk for 2 minutes to my vet who will get it in for me if they don't have it in stock.
