Having sold for PayPal for past 5 years , and having access to all data, I can safely say we do not acquire customers from a merchant.. we have tried to figure out how. We only give our customers to merchants. The largest brands see on avg 65-70% net new, smaller guys far more... nearly all of them... So sorry, but only the upstarts will be "acquiring" new customers via merchants, as they have no consumer base to bring to the table. Nice try.
