Grinded up weed is usually advisable not to buy just because you can't see the condition of the buds beforehand. Ground primo and ground bunk look very similar- especially to new smokers. Just an easy way to scam people is all. Pics, though? That'd probably help
I hope he gave you a good price... as for the quality you'll find out when you smoke it. Maybe it was from the bottom of his bag or something.
Looks decent enough it doesn't look ground up it just looks like the weed in the bottom of the bag. I wouldn't say you got jipped or anything at that price. You got some guys on here paying 50 for an eighth that looks worse. Special Queen #1 https://forum.grasscity.com/index.php?threads/Attempt-#2--(Special-queen-#1).1432973/
