Why is there such a difference in pricing. I found some Northern lights X Big bud for 17.08 (Rhino seeds). The same seeds on another site were almost $50. Is the quality the same why the difference in cost

. I am almost ready to load up my second grow (shiskaboom clones from a friend) and while they flower I would like to start my next mother fplant from some seeds I have read about on line (Afghan, Northern Lights or...). I have been burned before ordering on line (SEEDS DIRECT SUCK) so before I throw another 100 dollars out the window, I thought it might be a little safer just finding some less expensive seeds and building from there. Has any one bought seeds from Rhino seeds, is there a dependable seed suplier to the us? any help will be greatly apprciated.
