The +1 sweet seed per 3.pack or +2.per 5 pack is prepackaged by sweet seeds and last as long as supplies remain. Sweet seeds updates their sales often and if it's 3 weeks after a new drop. As far as wrong seeds, DM seedsman on Instagram, they will comp you. With my 4-20 order I wanted blueberry as one of my 14 free seeds, I received bubba kush(one of my least favorite) and they not only gave me a 10% discount, but also will be sending me a free 3pack of blueberry.. that's the only issue I've had with seedsman ordering every 3 months since mid-2013 and it was resolved within hours. I'm surprised they were even awake when I DM'ed. Seriously contact them, they will resolve your issues even only 1 seeds germinates out of a pack, a new one will be sent. That happened to my friend a couple years ago and it only took 2 messages, one saying the issue, and another giving order number.
