Well, you pay the price for the quantity. Therefore, over time, ten dollars became equivalent to however much was sold for the price, usually around .7 of a gram. So a dime bag equals .7 grams since it was considered a fair trade for ten USD. Finally, .7 grams = 10 USD, but in the Phillipines! .7 is equal to four USD. You save six dollars, and if you wanted to you could still trade four dollars for another dime bag! That means I could afford a sack with the pittance I receive after the day's strenuous labor, and it would take the sweat-shop workers a whole month's allowance... WOWZers!
