Well, I cancelled and got a full refund (minus 20 dollars) from Minersource, was pretty quick and painless.
Lucky for you..........
I've been dealing with Matt @ Minersource for 2.5 weeks...
Now that my order has been canceled. Still no refund yet.
At one point, I got an email that wire is on my way (which I never received).
It was $49 off what I paid for my order.

This is exactly what I'm concerned about, cancelling but ending up with both no order spot and no money back.
