I've mentioned Astrid of Astrid's Dutch Obsessions before. This site should be bookmarked in your cache and you should definitely sign up for the newsletter as she seems to almost constantly be having a sale, on top of prices that are already great. And, don't forget, she sends dutch chocolate which rocks.
Right now, she is doing free shipping on all Addi's worldwide (and she ships fast and the Addi's are cheap). Plus, the bamboo Addi circular's are 25% off. And she's doing some buy Gedifra get a slightly damaged pattern book free deal.
