Plus on private forums it is mostly vendors buying from suppliers. Ordering ten packs of LSD, or even grams of crystal, is much more common. The private forums where you can get such low prices tend to consist of big suppliers, vendors, retired vendors and suppliers, and their close online friends. If you are not in the market to spend $12,000 a month or more on drugs, are not a big supplier of drugs and are not good friends with somebody who meets one of the prior two criteria, then you don't have very good chances of getting on a private forum that has $300 a sheet acid. SR is way lower on the food chain, it is mostly random end level consumers buying ten strips for personal use. However it has been a while since I have seen really good L prices even on the private forums. These days $500 a sheet is more realistic than $350 or $400, and crystal is not very available at all.
