Pre-payment PayPal

Hi,



I have a question to resolve and I would like to know if anyone lived this situation or have an idea.



For example: I have an event in April 1st 2011, but all orders for this event via paypal must be donne 15 days before (March 16th).



Any idea?

Assuming the event is a “product”, make it’s availability from now up to 3/16/2011.

Then customers won’t see it after that date.

The idea is to be available from today to the date of event.

If today we have a client, he will be charged on 16th March and after this date the next clients will be charged automaticaly.



The concept to schedule a date to charge.



In PayPal website I saw “Bill Me Later”, anyone has already used this service?
