Made a buy from a reputable seller, product was good and all that. Rather than going through one of the markets (it was on AG but they are on another), it is ok to deal directly over email?
I realize that it means that it means no escrow, but it's a seller with a big rep here and on DNMs. I'd imagine they want to preserve their reputation, and I'm only doing a few hundred a time.
Yes, just make sure that you are using an email account that you created and only connected to via Tor. If you use your regular email account and the vendor's email is being watched, your home IP address will be linked to encrypted emails being sent to a known vendor.
You could use something like SIGAINT's free webmail service:
