Update: Received an email from bitinstant saying my order was processed.
And it has been, somewhat... Here's what I sent back:
Thanks, I received 1.6075 btc. About half of what I should have received. I entered $300 on the initial web page, but then entered $600 on the dwolla page. $600 was taken out of my dwolla account. I ordered around the 180s, so it makes sense (300/1.6075)=186~.
Ursay, can you open a ticket for this issue?
