I've found on iOffer.com interesting items that I couldn't find on any other auction site ! It is a valuable extra online tool, which I certainly will use again in the future to complete my collection of movies, CD's, vinyl etc. Warmy recommended from a Belgian user.
There are many choices, many different things to choose from. Often there are things that one just cannot find anywhere else. A great place to browse and often find what you're looking for. That is a wonderful feeling;-)
