We would like to pre-sell class credits to recurring events that allow the credit holder to purchase 8 credits and either choose to signup on the website for the event and pay with their credit card or simply show up and have their credits debited in person.
Thinks of yoga classes that occurs M/W/F from 5-6pm and the member can purchase 8 classes for $175 which is $65 cheaper than the drop-in rate. The user can then reserve a spot on the website calendar or just show up and the instructor will check them in and debit their credit. In one case we know they are attending, in the other, we do not know they are coming until they show up.
Also, when their credits get down to a pre-set level, 2, they are reminded to purchase again.
