"Enable multi-product subscriptions" - what is this mode?
This is mode when it'll be attempted to combine few subscription products into one subscription - opposed to default behavior of creating subscription from each subscription product.
But note that it's only possible if products have similar terms - same billing period, max length and free trial (if set), otherwise default behavior will be used.
Fr example you have two products:
- Apples $10 / week
- Oranges $15 / week
No other fees.
Client buys both of them and gets two weekly subscriptions - $10 and $15, but he could get only one for $25, which will have both products in it.
Also if there is signup fee for both products - it'll be summed up.
