I Don't think PB's ultimate Goal is to get around B2C Shipping Bans.
I believe they just want to be able to sell Puff Bars in C-Stores and Gas Stations when the rest of the Market is Forced Out. And are probably looking to Fill the Vacuum for as Long as the Can while things wind thru the Court System.
Or until Congress Amends the FSTCA/Passes Separate Legislation for TFN. Probably jammed into another Spending Bill like the Shipping Ban was.
