As per #992042: Donation name is not always used I am using this module to add an optional fee on the end that isn't a donation. My options are $0.00 and $20.00 but I would like them to appear as:
No subscription
Subscription ($20.00)

I suggest that this could be achieved in the textarea of allowed values like this
0|No subscription
20|Subscription

Then explode that on the pipe | character and if there is a description show the price in brackets next to it. If the value is 0 and there is a description don't show the price (although some people might like to show FREE or something like that)
