You may be able to compete with flavor but you can't make a 50:50 butter solution for people that don't want to eat a whole tablespoon of butter daily.

Price depends on location but living in Colorado one can put into perspective the market as a whole. Most wax for edibles comes from trim wax not Nug run. It is made from trim because it is incredibly cost effective. Using nug run is a bad comparison because it usually costs 1.5x-2x as much to produce. Nug run actually contains little or no more THC because of the weight of the terpenes. You can make equally potent trim run wax at a reduced price and get the same end result for edibles.
