This is true, OP, you could also use the card for accessories like a case.
They also have a promo where you buy 3 accessories, you get 15% each or 4+ you get 20% each. I bought a hardshell for my 15" and two packs of printer paper and the promo worked. I think it also covers stuff like ink, headphones, video game controllers and such.
Also, definitely YMMV, but if you say you're buying it for, like, your niece that's going to college, they might give you the student discount. Again, definitely YMMV.
