I'm a huge fan of Dorco razors. In addition to their normal prices on their website being about 60% less than razors from Gillette and Schick. You can also usually find a 20-30% coupon code to make them even cheaper.
The hilarity here is Dollar Shave Club doesn't even make the razors, DORCO does. The only thing Dollar Shave Club is builds the service around it, and does so well enough to have struck a nerve at Gillette.
