I don’t know the real answer but in my mind, a credit card statement is like a bunch of medical bills that you may or may not pay. Perhaps the combination of the billing statement from cc along w/ the next one showing payment might suffice.
Easy enough to nag the charity for a receipt though……..they should be able to see the gift in their records and send out a (nother) receipt. Occasionally it takes 2 reminders. More than that and you might wonder why you are giving to them………..
