Why is Nirvana cheaper?

Just shopping around, not planning a grow til next year but I've noticed Nirvana's seeds are much cheaper (about 30 bucks) compared to the other sites I've visited (closer to 90 bucks). And for the same amount of seeds.
Can anyone tell me are the lower prices a reflection of lower quality or just a good deal?

Yep and unfortunately that can have unwanted genetic side effects.

I've heard there is a couple of good strains they have though. Ask around

i took from nirvana 1 year ago only and i tried to get a seed from veg but its not giving seeds they are playing with genetics and plants not giving seeds

I guess you get what you pay for.

Yeah I got their bubblicious and half of them are the most retarded things I've ever seen, but the ones that weren't so bad are growing nicely.

I vouch for Nirvana Master Kush!
