That makes sense. And yep, I agree that with scales.. it's really a murky area because who's to say the buyers scale is calibrated right? Secondly, to play devils advocate, a less then honest buyer could say "Hey XYZ vendor, I ordered and 8ball but you messed up and only sent me 2 grams.. please send me the remaining 1.5grams or else I'll leave negative feedback" and essentially blackmail the vendor. Or in your case I can say "King I ordered 50 pills and you must have made a mistake and only sent me 5.. and I'm about to leave that in the feedback".. and yes you could (and will :)) tell the guy to go fuck himself and you would never make such a mistake or pull something like that, but then other buyers reading feedback would see something like that and hesitate to buy from a vendor. It seems that there is a slight unfair advantage against vendors when it comes to feedback. I am not saying the OP made up the .2gram discrepancy, (and by reading it sounds like the vendor just made an honest mistake).. but I wonder how vendors handle that fine line when their feedback/rating is on the line.
