I'm up in Seattle... This is a hot topic for me as of the last two years.
You have all these little punk ass dealers walking around with "The Shit", and just because someone tells them that their stuff is home grown, or BC Bud, or whatever they think that they can jack up the prices! Some guy tried to talk me into paying over $400 for a zip... I asked him what he was trying to give me, and he didnt even know what it was. Just that it was the shit and that I would be totally fuckered up.
Are you kidding me!?!? Stop contributing to that bullshit! Stop being greedy!! PLEASE!
Be reasonable... If you're going to charge $40 for 1/8 (and you damn well shouldnt be charging more) then toss in a little extra nug, just in case your shit dries up between now and the sale. I personally weigh everything before it comes into my possession, and right before it leaves my possession.
I think $40 for 1/8, $80 for 1/4, $150 for 1/2 and $280 for 1oz are seriously fair prices considering.
Thats just my 2cents.
