I had no idea CBD seeds were legal, but it makes sense.

Although you may want to be careful with that "worldwide shipping" thing. I don't think these are actually legal to ship worldwide.

Not sure where you're shipping from, but mocacinno is right, you should at least get some TOS / FAQ stuff going on, as we don't even know where this ships from.

Plus 30 seeds for 10-20$ sounds VERY cheap.

I never had drugs in my life, but still, it sounds very cheap to me.
