It's not just MD. I purchased two new Dianna Krall "pressed at RTI 180g 45 RPM audiophile" album sets at the DC Audio Show this summer from Elusive Disc. One Diana Krall/Live In Paris record had a nasty skip on one side. I had to pay return shipping. The replacement record was warped. I called ED, and while their written policy is the customer pays return shipping, they agreed to pay return shipping "this one time." I don't blame ED for these problems, but I'm not sure if I'll buy from them again. When I pay ~$50 for an album, I expect it to be in "perfect" condition - and if its not, I don't think I should have to pay return shipping.
On a positive note, I ordered four Gregory Porter 180g albums from Amazon. All of them were (are) in excellent condition. No quality issues whatsoever and they sound fantastic.
