They have a good rep, lots of people here have received seeds from them. I've never used them personally but I can recommend another site, The Attitude and use 420 at checkout.
Yes i have, i just received my master kush today and they sent 5 extra, plus it comes in a nice stealth package and a container that smells like chocolate coffee....2 weeks to get it to the day.
i order from them twice now.. first time the beaners dint germ right so i mailed them n they are sending me 5 more short rider fem autos. then my second order they sent me 10 free skunk type seeds.. i would def recommend them.. good customer service.. the site is Nirvana.com
