$10-$20 depending on your connect/how much you buy. X is pretty stable priced all across the country, seeing as there isn't anywhere to grow it easier/legal somewhere etc. Cheaper way up north though closer to Canada
He was saying because X is a chemical, its not like weed where its grown like in canada or mexico, so that people on the border get cheap prices, making it a pretty constant price throughout the US. Which is mostly true, but if you get deep into the rave scene you can get some great prices, or just happen to know someone who can hook you up cheap. Its no different from any other drug where you just have to know the right people. And for one roll, your probably gonna be payin $10-$20. Around here when people pick up jars (100 beans) they usually sell $10/pill, $15 for 2.
