Sellers:

I am amazed at how few sellers think to enclose paperwork for a sale on eBay.  Out of 20 plus items I bought recently from different sellers only three (3) sent any paperwork about the transaction.  What is the problem?  A seller has to process the sale and it doesn't cost anymore to put transaction paperwork in a shipment and done correctly, it will enhance a  buyer's perception of you as seller.  Paperwork can be a item that tells buyer's you are someone who cares about being professional in their transactions and will let buyers know that can depend on that seller to deliver as promised.

Buyers:

If you are sending payment to a seller, please enclose a note, copy of the transaction or at least a hand written note stating the auction/item number, the name of the product you won, the amount enclosed and a shipping address.  As I seller, I can speak from experence about getting a payment in the mail with no note enclosed then researching the auction to make sure I get the right item to the right person.

So buyer or seller, enclose paperwork, please.
