Is this surprising? There’s an online shop and it is open for business and inviting orders. There is nothing on the shop site itself which says that it’s actually a one man show and that you’re supposed to go and look at a completely different web site just in case there is a week old posting saying that orders will be delayed.
Even if somebody has seen the posting, they might just want to establish a place on the queue and be quite happy to wait. Your posting doesn’t actually ask people not to order.
If you don’t want orders, close the shop.
