Wife wants to use ebay to sell stuff, how does PayPal work

PayPal works very, but - you may have trouble withdrawing more than something like $500/month. Ran into that a LONG time ago when we tried to simplify the registration process for a youth event by taking credit cards - I think it took us months to get all of the money for that event pulled out.

Visa is apparently looking at moving into this space (but don't wait for them to figure it out - just jump in when they move to kill off PayPal :-))
