around here the prices go:
$45 an 8th (average...sometimes get it for $40 and sometimes for $50)
$90 a 1/4 (give or take $5 either way on average).
$150 a 1/2 ounce (give or take $10 on average either way)
$300 an Ounce (give or take $50 either way mattering on who you get it from.)
those are just averages...however i've gotten ounces for $200 a piece before...and even a half for $90...but thats just one of those, "You gotta know a guy" to get that deal...not an everyday thing.
if its for personal use then the sky is the limit on spending (mattering on how reasonably good strain is and a fair price.)
if you wanna sell it then you should aim to $10 or under at the least.
