One of our clients has a newsletter as a membership product to keep track of who is subscribed. This works well, except they still use the quantity field to see how many of the newsletters the user wants.
So if the user would like to pay for a subscription with 10 newsletters, then they enter 10. That all makes sense, however, I can't figure out how to adjust the validity of the membership to ignore the quantity field.
If someone enters 10, then the membership is renewed 10 times, and thus ends 10 years from the purchase date instead of 1 year. I would like for it to be set to 1 year from the purchase date, regardless of how many were purchased. If they want to renew, they would have to purchase the product again.
I can't find where the end date is calculated once the product is purchased. Any help would be much appreciated.
