You have to look at it from different perspectives.
Over the years, I've dealt with a large number of retailers in Canada who have been caught with counterfeit products of varying types, including hazardous goods. For the most part, the larger legitimate retailers don't want to sell the stuff. They want to compete on a level playing field, and they'll do what they can to get it off the shelf and to give the information. But they're buying from importers or distributors that are trying to deal in margins of pennies, and it's a really competitive area.
From the other perspective, you're looking at a lot of video game retailers and stuff. They're just counterfeiters and they don't care. All they sell is counterfeit product.
There are different levels of business and different perspectives. It's a multifaceted thing and there's no one quick fix to any of this. Although the copyright legislation with the penalties is effective, it's not being meted out by the courts or the prosecutors aren't seeking it.
