I recently discovered an excellent on-line auction house called e/bay through which I received some Goonies cards.  The site serves as a way for buyers and sellers to communicate with each other.

When you bid on an item it is sold by another individual not e/bay so the honesty of the sellers cannot be verified except through their history which is accessible on the site as well.   I have ordered many items through e/bay from many different sellers and have not had any problems yet.

When you get to the main page type goonies in the search field and you will see a listing of the items currently offered.  Other items related to the Goonies are sold here but the bidding is often fierce and the prices can get fairly high.  As with all on-line transactions, be careful.
