Avoiding the old bait and switch

Is it accepatble to ask the seller for a sample of of the bag you're about to get at the time of the transaction? I've just heard of guys trying someone's really good shit, then buying an ounce of it and getting home with a bag of ditch.

It's all about trust. This is why I have had the same guy for years. He wouldn't dream of doing that shit to me. As for the sampling, good luck with that, they may let you touch it and smell it, but I highly doubt anyone is going to let you smoke a sample.

no... as far as i am concerned, the only acceptable check for quality at the time of most transactions would be the opening of the actual bag you are getting to see and smell the contents.... other than that, you are pushing your luck unless you deal with close friends
