Just received my coins in my wallet, and awaiting confirmation.
Spent $105 and was supposed to receive $100 worth of coins, at $26/coin 2 days ago. I was given 3.83 coins at the current market price of $27.1 which is $103.
If you have an issue, just PM Yankee and he'll take care of it shortly. The market is crazy now with SO much volume and unstable prices. I'd hope they didn't buy them with my money at $23 last night and then sell them to me for $27 just now, but being a conspiracy theorist never got anyone anywhere :-)
I'll continue to do business with BitInstant because even if it took some extra time, I've received my coins and even though the email support for the website didn't yield any results, the fact that Yankee has been manually handling these cases on here says something.
Thanks Yankee
