Ok, I clicked on "Marketplace," "Vinyl" then "Seller" and this is what I saw Seller 564,766VinylExpressBV 535,041recordsale-de 388,8811207vinyl.dk 190,437FilkoMusic 163,665vinylminded 118,647StaxOfWax45 98,222bordentownrecords 89,655philadelphiamusic 76,784VinylShopUS 73,446Demonfuzz-Records Ok good, so VinylExpressBV got the biggest inventory. So I browsed and I placed a dozen or so records in the cart but after a while, I saw that all the records in the cart were no longer available! Clicked on "VinylExpressBV" again and I saw that their inventory has slimmed down to 23,000+. Later on when I checked again, their inventory went up back to half a million. So what's up? Is there a glitch somewhere or did I did something silly?
