I've seen that commercial a bunch of times and here's what I gathered...
When you can't seem to find a baseball that's been signed, that's on ebay.
A new toy you can fine a new suit that's been signed, that's on ebay.
Phones that ring, Organizer thing, pearlies on a string, jazz or swing, that's on ebay.
Buy today and it's on its way, other users say you will feel ok, that's on ebay!
