I'm not naming names, but it really bugs me when an online store doesn't update their out-of-stock items.  I odered some Artyarns Supermerino for a scarf along with some other yarns for CIC knitting.  I had an email the next day informing me that the Supermerino is on back order for approximately 3 weeks.  There was nothing at the site to suggest that any of the many yarns listed might not be ready to ship right away.  I realize that there is a lot of work involved in keeping these things updated but a clue to the possibility would have been nice. I won't be reordering from that store anytime soon.
