Even if you're not familiar with Logitech's standard gaming mouse filigree, the G502 is very intuitive. It features two center/top buttons, one for toggling the mouse wheel between "loose" and "granular" settings, and one for adjusting DPI presets on the fly. This is the case for most Logitech mice, but it's nice to get both options on such an affordable product, and one that also features multiple tunable buttons. The G502 also uses a handy LED-based DPI indicator for various settings—normal, fast, super-fast, and slow—so it's especially good for shooter scenarios where different weapons call for different optimal speeds.
Dell Home, via its Member Purchase Program, offers its Dell 15.6" Laptop Gaming Backpack in Black/Red for $28.49 with free shipping. That's tied with our expired mention from four days ago as the lowest price we've seen for this bag. (It's the best deal we could find now by $20.) It accommodates laptops with up to 15.6" screens and features a shock-absorbent EVA molded front shield, adjustable shoulder straps, and a deployable rain cover.
