Just wanted to put an update here.
I contacted OP and made an offer for 6 cards originally. We communicated mainly through email. Offer was accepted. I then asked if he would add another card to my list and made another offer. We agreed on a price for a total of 7 GPUs. He made a PayPal invoice and I paid it immediately. The goods were shipped and I received tracking info right away. I received cards today, with all of my cards boxed up perfectly. No issues at all. Great guy to deal with.
