Depending on the qaulity of the bud $20 can get me say 3.5-5.5 grams of some decent smoke.If it's a qaulity strain like skunk or some really good hydro it can only get me say 1.5-2.5 grams.I have paid up to $35 for 1-2 grams of some of really good stuff like northern lights/white widow,and some blue berry.
