I just realized that on my site I did not specify that if someone was paying via credit card on paypal that they should cover the fees. Someone bought a print and I ended up covering like .70 cents. Not a big deal the first time cuz it was my own mistake.... But then I got to thinking... should I ask those who pay CC pay those fees? Or is it my responsibility to include that in my price beforehand? If so, I would just have to raise all my prices and it would not be fair to those that pay cash or funded pay pal. In any case, SHOULD I be responsible for fees incurred by credit cards or is it the buyers?
