I want to start giving tips to artists after the art is finished, so I can tip according to how the transaction went, the piece itself, as well as how they may be pricing themselves. I used to tip up front, since there's a "give a tip" option.
However, when after the fact, I'd have to send it myself. In this case, since it's a tip and not paying for the actual service, would sending it through friends and family be okay? Because there would be no reason to get the money back.
If it's not good, what would be the best way to send a tip?
