uk.ebid.net - auction site

Not so much as wanting to trade, more drawing your attention to the above. It's like ebay but doesn't require you to use paypal (though you can if you want to)

It has a bunch of old stuff up for cheap (including the old mid 80's citadel journals and compendiums currently up for auction)

I've used eBid a bit, buying several times from two different sellers. It has worked great, apart from the google translated interface which is a bit annoying. It insists on translating the site to Swedish based on my IP. =( Bargains to be had, though my favourite sellers aren't active any more. Guess I put them out of stock.
