uhh.....an ounce? never heard of a "200 sack," but it seems like a reasonable price for an ounce of -good- pot. it depends entirely on where you live and how good the weed is. my guess, since you're in ontario, would be its going to be an ounce or more of some pretty freaking good homegrown mids, or else a smaller amount of some really good nugs.
Mids? No No No, my friend... no. We here in Canada have mids and schwag encrusted in amber-crystals inside the museum under "1500-1600A.D.". Our mids and schwag are just lesser grades of dank. We don't judge the coarse details, we judge the finer details. I can only get an ounce (or more) of dank or possibly (quite possibly) lower-grade funk. ...And don't think I'm a noob that can't tell the difference between good and bad weed. I've been around weed since I was 8, and smoking since I was 11. I've had shit and good weed, shit weed from when I was in Daytona, Florida in February. SO, no. I wont be getting shit weed for 200 bucks, and the dealers are generally very generous (you can usually get about 3.5g of good dank for 10 bucks (CANADIAN CURRENCY).
