well dude normally with dellers they dont just add up what a gram costs x3. what they normally do is give you like an eighth for the price of 3 grams not 3.5grams. so prolly $60 instead of $75. some may sell cheaper but they usually take a few dollars off the price when you want like an eighth, quarter, half, or ounce. like i sell my stuff for an ounce $350. selling it for 20 dollars a gram and then 28 grams in one ounce so the total straight up would be $560 for 1 ounce. but they save 210. thats normally how it normally works. i would ask for the price of an eighth ahead, do the math, then consult with they man about buying.

like stores usually do its better to buy in the bulk
