You pay for it the exact same way you would pay for any item you purchased on ebay. You just accept the second chance offer and she hits the send invoice and you get the invoice. You don t have to give the sender any info. I give second chance offers all the time to my customers. It is no different than winning an auction. In fact the second chance offer shows up on my list as a buy it now for just you. Once you accept, she should just hit the send invoice , ebay automatically sends the invoice and you get the invoice saying pay now, which takes you to paypal. No different. She does not need your email or anything else - ebay has it and so does paypal. Unless this is being done off ebay, which I wouldn t suggest you doing, because you can get stiffed.
All she needs is your email to send you the invoice, don t provide passwords or anything (you know that), then you ll receive an invoice in your email from paypal requesting payment.
