To a certain extent, I agree, greensleeves, but if they don't have the stock to fill the order, they should either have that noted in the ordering system (many companies don't even let you order if they don't have inventory). As that isn't the case, they should have at least responded to say, "Oops, sorry, we don't have any right now".
The problem I would have with this company is that OP says that her credit card was billed the day after the order was placed. That is a very bad business policy, IMHO, and I've never heard of it being done. You shouldn't be charged until the order is ready to ship. It seems like they are basically using your money while you wait.
I do not know how their prices compare, but I have had excellent service from Wawak, which I'd never heard of until early this year. I only use Aurifil, and have not found a better price anyplace. Orders go out the next day.
