I've never run into someone who asked until just last week. A bride asked if she could pay for $170 work of engagement prints with a credit card. We have a good repitoir so I told her that if she wanted to pay by CC I could accept a Paypal payment. (PS- she has paid for everything else thus far with a check) I know that moving forward I should probably set something up that is more official, but was curious as to what everyone else did. I've used a CC (debit) to pay for portrait prints before, but it was a high end photographer who averages $1000+ per client. That's not me. Yet.
