yes, I have boughten k like 50 times, and matter of a fact sold k for my friend making it, you should be getting no less than .25grams , but if the dude not an asshole, maybe .50grams.
In a club a good bag will be about 200mg and slim one would probably be like 100mg.
Best way to buy is outside of the club or party of course.

The music never stops...
Actually, a "twenty scak" will have EXACTLY 166.67mg, there will not be a difference of so much as a microgram, if there is, it's not a "twenty sack" ...
