Your situation could be different, but I purchased some keyboards from them last week. My bank denied the charge because the fraud dept of the bank thought it looked like a suspicious charge (large amount and foreign). I confirmed with the bank that the transaction was okay, and then the charge was allowed. Overall, I was extremely pleased with the communications and service at midiworks.
