CBSubs Plan pricing based on options

I would like to calculate the final price of a CBSubs plan based on options selected during the registration process - is there a way to do this please?

So for example:
Basic membership = $100
If a user chooses Option a ($50) + option b ($20) + Option c ($12) during registration then the total plan cost is therefore $182

Thanks a lot

You can increase the price of a plan using a negative promotion. So for example a promotion with -50 increases the price by $50. You can then have the promotions configured to apply if XYZ field option is selected. Currently that's the only way to do what you're wanting beyond having multiple plans with different prices that are conditioned to display based off option selection. Another alternative is to use a parent plan with the options being child plans of the parent, but you'll run into issues with renewals since you can't renew multiple plans at once.
