No problems ordring seeds at all – its legal.

The seedshops that gets five stars from me (all of them are really nice shops, with good customer support):
pickandmixseeds
Herbies headshop (they also have a pick and mix shop)
Sensibleseeds
therealseedcompany

And I think hemcy.at is very good, but I havnt order from them yet.

I doesnt recommend seedbay and topseeds – their customer service really sucks.
hempdepot.ca have nice seeds, but have only one payment option – send money by mail.
