It's pointless to waste both your time and the buyer's time by requiring them to submit a "support ticket" - strange way of doing business, by the way - just to find out your rate. Post it on the OP. There literally is no reason not to unless you actually intend to mislead the buyer. No offense intended. It's just nonsensical to post a trade thread without a rate, and then to have the buyer have to inquire about the rate, which is held constant (it's not like it's different on a per-buyer basis). So just to make it clear for everyone, and to save some significant time on the part of sayulita and the forum members:
The rate is 13.2% over Bitstamp.
