Probikekit has a sale, buy four Conti GP 4000S tires get 15% off. Free shipping for four so that's $34 per tire. It's 10% off if you buy two so still a good deal. Ships from the UK so delivery can vary from 10 days to 4 weeks.
Great price and great tires. So happy I was able to use them yesterday on a cold, wet, and very hilly course in the Pocono mountains. I would have killed myself on the switchbacks if I'd kept my Michelin Pro 3's.
