The first seeds I purchased were from a shop in Boston, $75 for 5 seeds. Wasted 3 seeds because they were regular seeds and 1 was male - so with the remaining seeds, growing one at a time. Amazing stuff, so worth it.
But I mainly buy from Seedsman.com, and bulk order. The larger the order, they throw in free seeds.My last order was for 10 Gorilla Glue seeds & 5 Silver haze for less than $150, plus spent extra for "discreet" packaging - which is worth it, cos first time, my seeds were nabbed by the Department of agriculture - but because I paid extra for the discreet shipping, that meant that the resent the order at no cost to me and the seeds were really well concealed...
