Usually Paypal for me, but I've used Venmo too. Either are ok by me. ^^

Cool! Thank you so much for replying. Ive been out of the loop awhile :)

One thing I forgot to mention is that it looks like Venmo is run by PayPal, but artists have had more issues (account suspension, etc) by going with PayPal directly.

I have had about 5 issues with PayPal as a commissioner of art, but all of those issues ended up being temporary.
