Bespoke Plus is $5 and Pro is $15; there should be no check in the $5 line for Pro, OR if both lines are checked, the second line should be $10 and not $15.
It depends a bit on interpretation: if you pay 15, you of course have also 5 fewer in your pocket, so the 5 fewer can be included in the 15 fewer, than it's correct.
Replies and downvotes mark a strong disagreement. So okay, my interpretation is not mainstream, but I still think it's a possible interpretation.
The difference in interpretation comes from the nature of "features": are they actions or verifications? A verification is (usually) idempotent / has no consequence on the state of the world, but an action isn't.

As it is it means Pro is $5+$15=$20.
