<top posting fixed>

Yes, I'm familiar with how it works.  You can use PayPal's API to send 
the data to PayPal (and get a result back) or you can direct the person 
to PayPal and hope they click on the "Return to...." link.

And a database is the best way to do this.  If you think it's overkill 
you don't understand how to use databases correctly.

Also - please don't top post.  Thanks.
