Ok, I want to do the following (registration for an event a month away): offer a payment plan, which allows users to pay 25% (or a set amount in $$$) upfront as a deposit instead of the full amount at the time of the registration/subscription, and pay the remaining 75% (or again, the set amount in $$$) three weeks from now (one week before the actual event) or on a set date... how would I set that up in the product page? ........... also, how could I set up a coupon that can only be used AFTER a user has subscribed for a certain product/service to offer him 50% savings on that product in case he decides to buy another one? never mind, i figured this out... just set up product Y to be unavailable in case the user has expired subscription to main product X or an active subscription to product Y already. genius.
