Geez! I've waited almost a week since I had a buyer use BIN to make a purchase. I've been anxious to receive the payment and make shipment, but I never had any contact from the buyer. I sent a PayPal invoice and an Ebay invoice two days late hoping to spark a response. I even went to his feedback to see how active he has been, and sure enough he's been around since he made the purchase and he has a decent history of payment. After reviewing the old thread, in my quest to create a FAQ for the BB, I realized that I should probably send a regular email, that PayPal and Ebay may be considered spam by his ISP and could have been filtered as junk or deleted if he thought it was an invoice for his own account. I sent a plain email this morning, copying the details from the PayPal invoice and made the subject "payment request" to reduce the chance of being blocked by the spam filters. I was afraid if I referenced ebay or an item number in the subject line that it could be deleted before the recipient got to read it. The buyer finally responded this afternoon that a payment is coming. Yay!
