I pay £20 for an 1/8, and get given 1/4 as the dealer knows my mate well who i pick up with, and doesn't so it by weight, so i got 6.2 grams if i remember correctly, and 7 grams is a Q isn't it? as i remember reading on here there are 28 grams in an ounce.. (i asked my mum the other day how many grams there are in an ounce and she said something completely different than 28 grams, and she proved it by showing me some scales lol)
