Around here you can just check the website called - weed maps. They have all the dispensaries and full menus. The dispensary I go to sends me emails about prices and specials. They have 25 dollar 1/8's on mondays but it's their choice what weed to sell on monday. They change it up every week. The same with the 150 oz. friday. There's probably 100 dispensaries around me though so there could be even cheaper prices. I got an oz. of low grade for 89 dollars at caps by the way , it had seeds and shit though.
