I bought a record of ebay and spotted the seller had one poor feedback for a record he sold, most of his stuff was baseball cards and the like. The bad feedback critisised how the record was packed. My record arrived safe and well in a 18" x 12" x 6" box, in side the box was a load of crushed newsprint packing, a wad of bubble wrap, inside which was the record with two pieces of cardboard either side wrapped around with duck tape.
I think he had taken the feedback personally
I paid $8 postage the box cost him $17 just to post
I sent him the link to bagsunlimited
