PayPal payments are sent using MassPay, so you pay no fees to receive the payment, however the convenience
fee is a little higher to cover the costs on my side.
A vendor of mine accepts for payment only credit card and PayPal currently. I do know from her kvetching that she loses 3% or so in fees each time I pay her. I'ld like to make use of CoinCard to help with that. If I use for the paypal address HER address instead of mine, then when she receives the payment from CoinCard she'll get the entire amount that was sent -- no fees to her!

Would it be possible for CoinCard to include an optional memo / comments field that will be included with the payment?
Well, two problems. If for some reason she says she couldn't find payment, I wouldn't have a transaction number that she could use to search for the transaction either. Would it be possible for the acknowledgement page (after my bitcoin payment to CoinCard is received) to display the PayPal transaction number as well?
At some point hopefully we can just skip this silly step of using PayPal as intermediary and I can just to send her payment in bitcoins directly where she, in turn, uses bitcoins to pay her vendors and staff. Until that time, however, I'm happy to have CoinCard.
