How to get paid through Paypal account?

I'm trying to sell some used dvds in bulk to a store that can pay me through paypal. What do I need to set up in order for them to pay me? Do I need a business account on paypal (do they charge)?

You don't need a business account if you are only going to do this a couple of times. The only thing I would check on your existing PayPal account is whether the limit for receiving money is less than what this person is going to be sending you.

When you receive money through PayPal, they will charge you a 3% fee.

You need to go to paypal.com and open an account, you will need a checking or savings account to transfer money from paypal into.

Yes they charge you a percentage.

You can print shipping labels with postage and they will take that out of your earnings....it's soooo cool and easy to use.

You will also need to link your paypal account to your ebay account.
