There is no Paypal option for sellers anymore.

You must be signed up AND verified for Managed Payments now.

Edit. You can use AP for postage you don't have to use eBay postage labels.

You must sign up to Managed Payments (which should be done before listing/selling)

PayPal is not an option and has not been for over 4 years

You have to do all steps to sign up for Managed Payments, and be verified to sell

And you will have a hold on your funds as a new seller, but you must send your item within your handling time and not wait for the funds

I really suggest you read the selling basics before doing anything, it will save you a lot of grief knowing how selling works
