I'm not a craftsman fan, and I think I've only exchanged one thing there ever and it was legit--a 10mm wrench that was like 8mm.
But from Sears' management's perspective, they determine their pricing. My background is accounting and I'm sure that they have teams of cost accountants estimating the cost of returns by people. Then they factor that into the shelf price.
So, whether someone finds a tool on the street and returns it, or whether you inherit it from your grandfather and return it or whether one of you guys bought it online cheaply and returns it or whether another purchaser pays full retail and returns it, the bottom line is the same for Sears, no?
Does the guy paying full retail have more of a right to return something than a guy paying clearance prices online?
Sears keeps records of the returns (if not at the store, when they are all shipped back, ultimately a report is made somewhere). If Sears finds the returns to be excessive to the point where they start to lose some of their profit margin, the only real effect to a massive amount of returns is that the price would have to be raised to compensate for a rate of return larger than they have estimated.
Sears is NOT allowing a generous return policy because they are patriotic, think it's the right thing to do, etc. They are a business and they are making sure they aren't getting hurt in their profit margins.
Again, I'm not really supporting this guy--I think his logic is flawed anyway. He's saving tools for the end of the world and the ones he turned in were probably of higher quality to start with. My point is simply from an exercise in following the money, I'm not sure I see how this behavior hurts Sears?
