问题
I've read a few responses here regarding the modification of the recurring fee amount but still confused.
We have 5 subscriptions levels per month: £10 £15 £20 £30 £50
We want to be able to let customers change their subscription package to any of the other options.
It sounds like if they are changing to a package with more than 20% difference from the one they are on - we would have to make them cancel and start a new subscription.
Surely there is a way to have the subscriber confirm they are happy to change the amount?
thanks

User can modify your paypal amount, but some restriction are there.
In Standard account, you can use "modify" html variable to change subscription amount as below.
0 – allows subscribers only to sign up for new subscriptions 1 – allows subscribers to sign up for new subscriptions and modify their current subscriptions 2 – allows subscribers to modify only their current subscriptions The default value is 0.

you can not modify often your amount, you can only increase the subscription amount by 20% for 180 days.
but if you move to paypal payflow($30/month), paypal itself provide API to communicate with paypal service. its very flexible to modify, cancel subscription.
paypal standard - user cannot cancel subscription their self if they dont have paypal login. paypal payflow - user can able to cancel their subscription.
