I presume the serving size is that box of 3, correct?
On a separate note, I ran out of my regular bootlegged gummies so I stopped by a smoke shop here in ATX to pick up some hometown hero gummies. The lady working the counter told me if you buy more than one item, you get 10% off your order, so I told her to get me the cheapest edibles they had. She suggested this Qty (2) for $5 package which featured the cannabinoid THC-P. "WTF is that" I asked, and she said its really strong and lasts a long time. Whatever, I bought it.

Gotdamn! I ate one (8mg) at 6PM one evening and it took a couple of hours to get rolling but I was still BAKED at 1-2AM. When I woke up the next morning......still stoned, but not as bad. At random times the next day, I would become rebaked. Shit was something else. I may just throw the other one out as I dont need to be stoned the next day, lulz.
You definitely aren't getting that kinda mileage on $2.50 worth of booze.
