B&H Photo Video offers the Vanguard Endeavor ED 10x42 Binoculars for $199.88. This $80 mail-in rebate drops that to $119.88. (Amazon charges the same after rebate.) With free shipping, that's the lowest price we could find by $100, although these binoculars usually cost around $300 without a rebate. They are waterproof and fogproof and feature ED glass lenses, a 65.3° angel of view, and anti-reflection, Phase2, and V-Max Silver coatings. Rebate ends September 30.
