Walk into Fashion via Rakuten offers the Schick Xtreme3 Disposable Razors 30-Pack in Blue for $16.95. Coupon code "WIF2" cuts the price to $14.75. With free shipping, that's the lowest price we could find by $2, although it was a buck less in January. Each razor features dual comfort strips, a rubber handle, and lubrication for a burn-free shave.
None of these moves requires a big investment, and they all can save you money.
