I've bought yarn from them, but it was through a co-op, so I expected a little longer ship time. It wasn't more than a month though.
That said, their yarn is AMAZING. Every bit as soft and wonderful as Malabrigo, but a wee bit finer. AMAZING, I say -- I would buy a roomful if I could. One of my very favorite yarns ever.
(It's the yarn I used for this sweater
-- so nice for cables!)
