Do you know any good online payment providers easy to handle?
Paymill [https://www.paymill.com/en-gb/] it's a very reliable payment system to me, because of being fast and simple to handle. Transaction fees are affordable and it operates in over 40 countries right now.

PayPal is all I can come up with. I've heard of money packs and bitcoins, but haven't gotten started with either of those.
