How to add customers in bulk to a different price plan
When a customer has the choice between a free subscription and payed subscription, after the payed subscription has expired, he should get an email so he can prolong his subscription OR the subscription should be set to the free and limited listing if not payed within a certain period of time.
That would be the perfect solution, which is not possible as far as I can see. So another option could be to manually move a lot of customers in bulk from one price plan to another. But how???
