This happened about a year ago. I didn't want to tell the story when it happened in fear of reducing my OPSEC (HumboldtFarms could easily connect this story to my AB account, they have my address). Now I figure they do not have a time frame and I also don't plan on buying from them anymore so it should be safe. So I ordered 14 grams for 90$. A few days later I notice a message on AB from HB saying that they could not decript my PGP so they refunded me. I order again the same order of 14 grams, this time the PGP worked. A week later I receive it. Upon opening it I was surprised, all the bags looked large and when I got to the zip lock it was packed, Then I notice on the top 28.5 and then it hit me, in my hand is an ounce. I weighted it out and it was in fact an ounce. I thought I somehow fucked up my order and ordered an ounce so I checked AB only to find that I did in fact only order and payed for 1/2 an ounce. I then came to the conclusion that me ordering twice, the first one cancelled, must have messed up their system and they saw that I ordered 2 orders of 14 grams so they sent me it in one bag as an ounce. Had some friends over and we enjoyed the weed. It wasn't the highest quality but for 90$ an ounce I wasn't complaining. I contemplated messaging HB about it but I figured if I don't do anything I can just enjoy it and not have to worry about a potently angry vendor, especially because he was getting quite a few scam reports after I ordered.
If they sent you more than you ordered that is on them. Besides, HumboldtFarms moves so much cannabis that a half oz isn't shit to them.
