Weedseedsexpress describes itself as a seed bank run by growers, with every strain in the range hand-picked and tested. The company is registered in Haarlem, in the Netherlands, and orders are paid into a Dutch bank account.
Their catalogue is organised around three pack sizes rather than a different set per strain: 3 seeds, 5 plus 1, and 10 plus 2. That makes the price per seed fall steeply with the pack, from around eight euros for three to just over four for twelve.
They sell seeds as souvenirs and for storage, which is the wording their own disclaimer uses, and they note that germinating them is illegal in many countries.
