Yep - I can pay sellers this way, but we can't accept Paypal at the action...here's why:
Paypal has a very bad policy when it comes to refunds...If the seller (that would be the auction) doesn't have a shipment record from a major shipper (e..g. UPS, Fed-ex, USPS), they AUTOMATICALLY will refund the money to the buyer. No appeal process, nothing. My partner (Jon Huston) actually had this happen:
1) Seller bids on and wins an item
2) Pays for the item using paypal and takes it home
3) Seller "disputes" the payment with paypal.
4) Paypal credits sellers account and debits Auction account
5) We're out the item and the money including the amount we paid to the consignor !
