This deal has ended.
Through 8/15, Buy.com has the Logitech V220 Cordless Optical Mouse for only $14.49 after this $8 mail-in rebate. That's just $1 more than in our last mention and that model was refurbished! Plus, shipping is free and there is no sales tax (except CA, MA, MD, NY, TN). The mouse features a 1000-dpi optical sensor, side-to-side scrolling, and is compatible with either Mac or PC.
