When I'm away for 3 days and can't ship, I don't close the store, I just change the handling time to 3 days and make an announcement in all my listings, which buyers usually wouldn't notice anyway. So, on top of that, I'd like to send out an auto message when a payment is received. But it seems that eBay only can send out a pre-prepared message, not a custom one. Did I miss something? Thank you for any help in advance.
