I was looking for an old 60's album and found a few here. I chose the one that looked like the best condition and price. There were no shipping charges displayed, so I assumed I would see them on the next page when asked to pay. So I clicked Place my Order (which I assumed was like "Add to Cart"). I was appalled when I saw $30 shipping charges for $8 album. So I ignored this seller and clicked back and tried another, which turned out much cheaper on shipping and placed that order. Little did I know I had "committed to buy and pay for" the first album even though I could not see the shipping charges. So 4 days later I get a crappy email from the seller saying I didn't pay - I thought he was crazy as I told him I wasn't going to as the shipping charges were too high. Well he still marked me down, the 2nd one marked me up, so I have a 50% rating, which now is not enough to buy from many sellers.
And while the seller can rate me, I can't rate the seller. Discogs support is automated and useless. So now I'm stuck with a 50% rating through no fault of my own.
