Amazon offers the Nikon Prostaff 3S 8x42 Binoculars for $89.95 with free shipping. (Best Buy charges the same.) That's the lowest price we could find by $15. It features a fogproof and waterproof design, 8x magnification, 378-foot field of view at 1000 yards, and a center focus system.

Note: It's on backorder, but can still be purchased at this price.
