Well, I finally RTFM (or brochure – I have an excuse: I’m a guy; we don’t RFMs) and it turns out that you get your Warranty purchase price back, not in real (that is cash) money, but in a Staples cash card, redeemable, of course, only at Staples. So if you don’t give Staples their margin on previously purchased service within 2 years, they get it in purchased products after 2 years.
And that’s brilliant! I don’t understand why more companies don’t do this. For example, when I buy tires, I always turn down the “extra protection plan” because I know it’s an insurance product and I’m better off self-insuring on all the tires I’ll buy over my lifetime. But if I got that plan’s purchase price applied to my next set of tires if I didn’t use it, I’d take it every time. It’s win-win.
