This is how they operate; I would take the store credit they give you and get whatever interests you, but there are better places to get seeds from from here on out.
I actually am harvesting a Girl Scout Cookie Extreme from them tomorrow (alongside some mephisto autos), and it looks great, good looking resin, nice tight dense nugs, and a sweet smell!
The problem is that it's one plant among other that have had issues. My winter/spring grow I ran 4 of them and had all but one herm and the one that didn't herm foxtailed. The smoke wasn't bad, but at this point I've run 7 of them and I've given away another 6 of the 20 seeds I had and the phenotypes are all over the place.
There are some good phenotypes among the seeds that they sell, and you can definitely grow some nice stuff, but why bother? Their customer service is good, but their seeds aren't cheap and their consistency is poor.
I've been running Humboldt Seed Company alongside them for my last two grows and I don't think I'll ever go back. Their seeds are reasonably priced, I've had great consistency, no herms from fem seed, and never had a seed fail to germinate. The terpenes are fantastic, and I've loved the smoke (Magic Melon was a huge favorite w/ my family that smokes, but I ran Caramel Cream, Blueberry Muffin, and Hi-Biscus alongside it and loved all of it, though I flipped the last two much earlier/smaller than I ordinarily would have and didn't get a ton from them, that does not look to be a problem with my current grow)
