I wonder how it is possible that some products are sold on EbayeBay via auctions for oftentimes half the price that they cost e.g. on Amazon?
EDIT: The productproducts that I have in mind are headphones by a quality brand that cost ~120 on most sites (including Amazon and their official Teufel website) but on eBay you get them for around 80+ if one uses the "buy now" option and for 60-75 if you take part in an auction. Furthermore the price varies considerably between different sellers for the "buy now option" on ebayeBay.
