At this point in time, additional pricing is not available for bundles - something we'll be introducing ASAP!
For the meantime, you definitely can still sell the same bundle at different price points - you just need to make two versions of the same bundle (i.e. two bundles that both include the same content, but with different pricing).
If you have any questions about this, then please let us know below!
Definitely something that we need as well - would make things much cleaner for us, especially now that coupons are persistent.
