The easiest way to get money into the account is to have it connected to a bank account.
As others have said, find a fee free bank.
I told my bank that I just wanted an account for when I ordered online. Something that was separate from all of our other money - just in case the unthinkable happened.
They said "Ok I understand", I deposited some money and I was in business.
I connected my paypal account to that one and if you use paypal to pay for anything, they just deduct it from the bank account.
If people buy from you, they can pay into your paypal account. If you buy something and pay with your paypal account but not enough $$$ is there to cover your purchase, they automatically go to the connected bank account to make up the difference.
So, once you have a paypal account - open the bank account.
Clear as mud?
