do seeds go bad?

[Exclamation221]

I was considering buying seeds right now and then growing in my greenhouse with regulated light, but the only problem is that I have to do much more research to know exactly how to proceed. My question is, If I get seeds and have to wait maybe a month or 2, can the seeds go bad? Also If I waited much longer so I could plant outdoors next season, would they go bad if I got them now? Thanks for any help.

Seeds don't go bad that fast.
Keep them dry, reasonably cool, and in the dark for best 'shelf life'.
You will certainly be fine for the spring.

Actually, I've heard of seeds being viable after years in storage.
