I've had a number of seeds confiscated by Customs. All you get is their standard, "We took you seeds" letter and that's it. I've learned
who not to order from and that it's best not to order from a store that sends their orders from the Netherlands. The only store that has fulfilled every order I've placed with them is The Attitude. AND....they're pretty quick. My last order with them was placed on a Wednesday and I had them in my mail the next Monday, (I'm in the US).
I took my kids to Amsterdam a few months ago and wondered if I was going to have any problems. I've received at least 4 letters from Customs and thought they might have put my name on a special list. I had no problems at all. In fact, if I'd have known how easy Customs was going to be, I would have brought some bud home with me. So don't sweat it! Peace!
