Personally i'v orderd only from one site ( www.herbavigor.com )
Click on the disco ball, then scroll down to the 'Cannibinoids' and you can get pure JWH-018 for a Price of: 1kg-$16,000; 500g-$8500; 100g-$5600; 50g-$2900; 25g-$1,900; 10g-$1100; 1g-$120 ...So its not not rly that cheap, but you gota remeber it doesn't take much to get a high comparable to pot (remember its 4 to 5 times stronger then weed...thats so true!)

All the stuff listed on that site are perfectly legal highs (In the USA ONLY)
But not ment for human consumption ... just tell them its your bonsai fertilizer if anyone asks haha
