Give me an education about this "PIRATE SHIP" method that has been discussed here.

I signed up with Pirate Ship awhile ago, when members on this forum were beginning discussions on shipping costs, and mentioning this Pirate Ship company.
BUT, i never gave them a payment method, when signing up, figuring i probably never will be using them.
I got back into my account, and my primary payment method will be Pay Pal.
I always keep a balance in Pay Pal, so telling Pirate Ship was so simple easy to do.
Anyone reading through this posting, and thinking about signing up with Pirate Ship, go and do it.
Super easy, and don't put it off any longer.
