Perhaps they confirmed "receipt" of the order, but not necessarily that it
would be shipped or that your CC has been approved. Instead of speculating,
if concerned, contact Woodcraft for an explanation. They would know more
that we do on the subject.

I did call Woodcraft. The morning after the sale as they sent an
email saying one of the line items was cancelled (I was fortunate to
have gotten two line items delivered unlike others who had their whole
order cancelled). I don't see it being a CC issue as they shipped a
partial order. A cc issue would have cancelled the whole order.
Their explanation went something like this: We're sorry but our
systems couldn't keep up with demand. Consequently, orders were
placed and confirmed but the inventory had already been sold. My
gripe with Woodcraft at this point has to do with them not being
properly prepared to handle such a sale and their unwillingness to do
the right thing after the fact. They'd do much better to simply eat
the cost of filling those "confirmed" orders and retain their customer
base.

I work for Intel and learned a lot from how they handled their
Floating Point issue on the Pentium several years ago. That screw up
cost the company $500M and lost a large number of customers.
