				 RE: Buying 'cash' with cash? 
 
			
			Something to look into would be the PayPal IPN.  A good tutorial is here:http://designertuts.com/paypal-ipn-receiving-instant-payments-in-your-web-application/
 
 I've not personally had experience with the PayPal IPN, however it is something I will probably be playing with at some point in the future to automate things here.  It's a good place to get started though for handling PayPal payments on your site. :)
