Working at best buy, I find quite a few things funny.
One is Reward Zone. Often, I will toss it in free when people buy a computer package. If the package costs 1500 bucks, there's 75 in their pocket. Kinda cool. Of course they have to spend the money at BBY, but it's all good in the end. Creating customer loyalty is what it's all about.
Oh, and the product service plans and replacement plans... We actually lose money on those regardless if what people think. Actually, best buy loses money every time a product goes out the door. The only way best buy makes money is by having those large manufacturer displays and endcaps, basically like banner ads on a website.
