To Receive Free Samples or Not?

In the past week, I've been offered free beer samples by two international breweries. The first I didn't bother to capitalize on--Newcastle Brown. (They were offering half-racks, which tells you something about the beer.) But today I got an email from Warsteiner. Now, I don't have a moral problem with taking samples--it's understood that such a small transaction doesn't constitute anything more than an opportunity to be reviewed.

But the bigger question is whether you care about random foreign breweries. I want to keep the focus of the blog on local beer, and I assume that's where your interest is, as well. On the other hand, you know what they say about assuming...

So should I make it a habit of turning these down? That's where I'm leaning.
