my best advice is never offer more than a 20. don't ever let them know you have more than a twenty.but they also know that,so if you get offered an amount that looks good for a twenty where you come from;go for it.I get about a 1/2 oz easy in jamaica of the best ganja you'd ever wanna smoke with a 20..but if you offer them 40 for it your screwed because then its a 40$ 1/2.yousee how the economics work.don't jew them too harsh,its disrespectful.don't always agree on the first price,that takes the fun out of the game.be safe,have fun,score with a friend or somewhere where there's folks in the vicinity,it cuts the chance they'll rip ya and run.but I've never been ripped or burned anywhere in the caribbean,the weeds to plentiful and cheap.its coke thats the big deal down south.be cool ,'Buz
