If my love of office supplies doesn’t seal my dork deal, how ’bout we throw in a calculator watch?! Don’t care what watch snobs think- when I’m in Target trying to figure out how many inches of drapery panels I need for a job, it feels like just about the smartest $25 I ever spent. Plus, it goes with everything, and everywhere… including the shower and beach. If looking cool while doing math is wrong, I don’t wanna be right.

CASIO Calc. Watch, $24.95

If you love the price, but don’t find yourself handling the same level of heavy duty equating whilst at Target, this other guy is also adorable and affordable…
