Uh ... what are you asking? If I understood your question ...
Tobacco tax is based on wholesale cost ... not MSRP. But, if you know what the tobacco tax is in your state (I posted a link here not too long ago), if you add that to the MSRP's in the above link ... that's roughly what you will be paying.
Remember ... is going to be very rare that you will get MSRP for Opus X, or any other hard to find, high demand cigars ... LOL! Supply and demand will always command a higher price ... and the tobacconist knows they will get it.
Good luck!
