I have only purchased two items so far, and this worked quite well. However I'm a bit disapointed by the site, because I thought it is for Amiga/Retro enthusiast, but I have the impression that most sellers are the same as on ebay.
And yes, the site is really sloooooowwwwww.
What I also find a bit annoying is, that I always see this endless banner of rules. I mean, I already read it once, so why do I have to be hit in the face with it, everytime I load a page?
