Haven't see $80 oz but $100 is common now. Some of the stuff being flogged for $600/lb here is pretty nice. Also funny now BC gov owned stores are breaking their own rules and opening by schools lol.
The problem the stores have is you're selling low profit margin products as small amounts. you'll need huge daily traffic to make profit. Most of the pleces here are in high visibility retail locations so can't see their lease not being 7-10K per month. Add in two employees $5K before taxes, your own salary say $5K before taxes and not including any partners so you need $20K min per month. With 100 customers per day buying 2 grams and say $2 profit per gram average would be $4 profit per customer so $400 profit per day or $12K per month. So you'd need 200+ customer buying more than 2 grams per day and you probably just spend $200-400K to set this up lol. I know someone who set one up and I think it cost her around $300K to get it set up, this could be with stock included. Add in 2,3,5+ more stores per city and you're fighting for legal scraps.
