kansas- look at these:
seedboutique.com
seedbay.com
cannaseur.com
I have successfully ordered from all. I'm in the US.
Check maturation times. Some Nirvana Afghan x are longer than pure afghans. Afghan #1 is a classic though.
Seedbay has pretty good deals.
Cannaseur has the best strains in terms of the really new releases that are going to blow your mind.
Seedboutique is like seeds in the mail voila. You send US cash, they send seeds, the whole transaction is reliably under 2 weeks.
Good luck
