Non-US sales of Biotest represent less than one-tenth of one percent of overall sales. Shipping to Alberta usually means seized orders, even on protein powders. (I heard of one guy getting a dipping belt confiscated!)
Then the Alberta resident wants Biotest to send it to him again and eat the loss. It’s just not worth the hassle. Biotest can’t spend all their valuable time dealing with a microscopic area of sales. They’d have to neglect everyone else if they did. That’s just not realistic.
Be mad at Alberta’s policies, not Biotest.
Hey, there’s some European sports cars I really like, but the US won’t allow them to be imported. I don’t get mad at the car maker, I get mad at the US policy. And if it bothered me enough, I’d move. (It doesn’t of course, just using that as an example.)
