Techically if you were breaking up an ounce and selling it in 1/8 this is roughly the price they would cost but when buying a whole ounce at once you should get a reduced wholesale rate. I wouldn't pay more then $180 for a ounce
Lab caps? Sounds like bull shit to me. And that is way too much, this guy does sound like "your boy" he is custying you.
No such thing as "lab caps".. there are shrooms known as liberty caps, but it is highly unlikely that you would ever find any if you didn't pick them yourself.
