Well when SHTF, there will be a party at your house WOOHOO!!!! lol just kiddingI'm sure they have a longer shelf life then the stores, they do that so that they don't have to deal with customers coming back and saying the seeds were brittle or didn't yield anything. More of a way to cover their own asses rather then anything else. I'm not going to say what kind of seed it was, but when I was in high school i found a seed of some medicinal plant and had it for over a 3 years, before I planted it, and it grew. I ended up giving it away as a "gift" to a different friend. I do not partake in that kind of stuff anymore.
