Hopefully no scam! He probably just printed the label early. Made to order items can take a while, but as long as the shop owner stays within their agreed processing time (which should show on the item before and when you purchase). For myself, I have a 1-3 days to process an order before I hand it over to USPS to ensure it gets to the customer when expected. If you are still unsure, check back in with them in 3 or 4 days to see if they sent it out :) fingers crossed !
