I have been ordering from them also, love their sale prices and variety of yarns. Thanks for letting us know they check things like dye lots, so important. They must be quite busy, my last order was not sent for almost a week, but then it arrived in just a couple days after it was filled. Anyway, it's not like I was 'out' of yarn, and needed it yesterday.
It's a very small organization and not open everyday. I don't expect to order from them and start a project with the yarn this week. They can take awhile to fill an order but IMO it's well worth the wait.
