OK I take this back. This discussion led me to wonder just how much interest SO is charging the new mechanic, and I suddenly realized it was possible to estimate. The interest charges are pretty significant.
There are certain tools that SO buys and rebrands, and I'm about 99.9% sure that Precision Instruments supplies them with several of their torque wrenches. I have both a SO and a PI torque wrench and they're identical, same case and everything.
The list price of the 20-100ft-lb split beam torque wrench is $175 from
Precision Instruments, and $250 from
Snap-On.
Let's say the SO guy allows you to buy the $250 wrench for $25 per week for ten weeks. If you imagine this as an amortized mini-mortgage, this is like paying back $250 on a loan for $175. In any kind of loan you always pay back more than you borrow, but the question is: what is the equivalent annual interest rate? I used an amortization calculator to estimate this, and it's about
467%
Of course, with the SO guy you're getting the truck and the warranty and everything, so the wrench from SO is worth more. Let's split the difference and assume that the wrench from SO is really worth $212.50. In this case, the interest rate drops to about 198%, better than before but still way deep into ******** loan shark territory.
So I guess there's two ways to look at this: one is that if you're a young mechanic with high credit risk, you're going to pay sky-high interest rates. Second, I love the Snap-on tools that I have, but man they're pricey no matter how you look at them...

Note: I assumed here that you made the payments at the "beginning of the period", that is you paid the first $25 when you got the wrench. The rates drop to something like 365% and 175% if you take the wrench and make the first payment the next week (paying "end of period").
I should also point out that I've only looked at one rebranded tool and these results might not be typical.
