ModCloth is getting into the Pi Day “fun” with a flash sale with 20% off a ton of science-inspired clothes and accessories. Everything from equations to dinosaurs to outer space (both real and fictional) are spattered about this flash sale. There’s no code needed, but it’s today only, so you’d better put a fire under that Bunsen burner.
