No good $500 ones. However, there are good options. 200s at office stores, occasionally 250s at giftcards.com. Anything from Giftcards.com needs to be ran in <$100 swipes though. Search around these forums to see the details of different office store cards. InComms are good for 500. I've also found it's ok to run multiple BHNs in a single transaction. So, depending on how friendly the CSR I'm working with is, I might do 3 swipes into my Discover (500 InComm + 2 BHNs). I do 500+200 into my Serve Amex (that's the load limit) and a single 500 into my serve Visa (again, the load limit).
