Browsing through the store, I noticed that seeds and a few other items have "Shipping Restrictions" listed under their descriptions, followed by names of a few countries, generally the US, Canada, and Germany. I'm curious as to what these restrictions entail: Is it impossible to get these items delivered in these countries, is it just a little tougher due to customs, or is it a risk you take when ordering that you may never get the package you paid for?
