Don't get me wrong: I'm not saying not to offer PayPal, it's a convenient option to have available. But artists - and any businesses - who lock themselves into one method of payment are running a big risk, and also turning away a certain number of legitimate customers who can't or won't use that service. Diversity of options is key.
That's great right up to the point where PayPal decides they don't want to do business with you because you draw stuff they don't like, or a commissioner complained and they froze your account - and by the way, you can't buy or sell anything on eBay while your account is limited; they're run by the same people and only accept cards via PayPal.
