Dollar Shave Club is offering a Free One-Month Trial with code D12S4C12 at checkout. Though three plans are available, the best bang for your buck is The Executive, which costs $9/month and includes 3 cartridges and 6 stainless steel blades. (Click "Do It" to view the plans.) Shipping is included on this plan. The best shipped price we could find on a similar bundle was $7, so that's essentially a $7 savings. If you decide not to continue after the free trial, don't forget to cancel within 30 days in order to avoid being charged the monthly membership fee. There is no sales tax (except CA).
