I don't appreciate buying an item that is not even in stock (from any online retailer). However, if I was the OP's customer and I really wanted that DVD, I would wait for it without any issue, simply because they informed me of the problem promptly. If I didn't want to wait any longer I would take the refund.

If I had to hang around wondering why it hadn't been posted and seller appeared to be stringing things out without any contact, then I wouldn't be a happy customer.

englishrose - do you think the OP's permanent ban is warranted? We know what he has done, no point in repeating it ad nauseum.
