If I were doing a business analysis of this, I'd wonder how warranty cost breaks down into the following:
- Cost of the actual replacement product
- Cost of handling the customer service
- Conversation with customer
- Receiving the old tool
- Cost of delivering the replacement product
If a home user warranties a tool, Snap On has to respond to the phone call or email. It seems reasonable to assume that it would take 5 to 10 minutes to handle this process of communication and filing the data into the system, generating a return shipping email, etc. If we assume a customer service rep is making $15/hour then after FICA taxes, insurance, paid sick leave, etc, that easily jumps to $25/hour. To keep numbers round, let's assume they can handle 5 warranty claims per hour, that's $5 in customer service fees per warranty claim communication.
Now they have to pay for a return shipping label, and a sending the replacement, let's call that $15 round trip since they'll have business tier pricing with UPS.
Add on the 10 minutes when the tool arrives to inspect, process it, put new tool in box, ship out, let's call that another $5.
So you're looking at $25 to process a warranty for a home user. It might be a single socket that cost them $10 to make.
The point behind this discussion is that in the case of Tool Trucks, Snap On has essentially offloaded the entire $25 cost to the Tool Truck driver. The driver has to deal with everything and the replacement tool will be included in his next bulk order and adds almost nothing to the total shipping cost.
I'd want to know this because if the ratio of Tool Truck customers to Home Users shifts, then the warranty costs will increase.
The point of this is to say maybe Snap On's warranty costs are much higher than listed, but they are cost shifted to a different part of their balance sheet. In this case, if they sell the tools directly to the customer, they have much larger of a profit margin. If they sell through a tool truck driver, Snap On sells it to him for wholesale prices, and some of that profit goes to the tool truck owner.
So they trade off having a lower cost to warranty but also have lower profit per tool sold. Versus selling it themselves, they'd have higher profit per tool sold but warranty cost would be higher.
