Spotted these guys selling bits on ebay. Whereas I normally woukdn't go for "retailers" that do this I thought I'd give them a try. I ordered some Eibach springs for my mk1 on Wednesday at about 11.30pm. The springs arrived by courier on Friday morning at 9.30am. Add to this their Pricebeat offer and I think that's very good service.
The only downside is that you have to register before ordering and wait for the confirmation email before you can complete the order. I had a couple of problems with this but Dan (presumably the owner) was online throughout and responded instantly to my emails.
