seed help ?????

HI CAN ANY ONE TELL ME THE BEST STRAINS TO BUY FROM NIRVANA THEY SEEM SOO CHEAP FOR TOP STRAINS THANKS FOR ANY HELP

depends on what you going for. if you look for a good strain to learn the fundamentals with and still end up with some great bud go for skunk#1 or northern lights#1.
if you got some experience on the book BB, cali orange, WW, citral, jock horror, papaya, bubble-something or blue mystic. i tried those all those, but have to admit i got stuck on BB, love those buds
