Pete - Tough break man. I agree with you on it getting through customs. They would have included a card inside the package (I believe it's green) that states what custom official took your contents, and why they took it.

I am betting that one of the sorting machines cought a corner and ripped it open durring the transit process.

I hope that you have a bit better luck. No one likes being let down. I would suggest trying the boutique again, but if you are not comfortable with that then I also know Drchronic.com to be a very reliable source for seed purchase.

Keep the Peace
