Buying multiple App Store bundles

Suppose I have 3 paid apps:

A1: iOS App Store only

A2: Mac App Store only

A3: Universal Purchase

and 2 bundles:

B1: A1 and A3

B2: A2 and A3

(As far as I can tell, it's impossible to have a bundle with A1 and A2.)

Is it possible for a customer to buy and/or complete both B1 and B2, and if so, how much money will the customer end up paying relative to the prices of the apps and bundles?
