BuyDig via eBay offers the Wenger SwissGear 15.6" Granite Laptop Backpack in Red/Black or Blue/Black for $28.95 with free shipping. That's $11 below our mention from three weeks ago, which was bundled with a $25 Dell eGift card, and the lowest outright price we've seen. (It's a current low by $19.) It fits laptops up to 15.6" and features a stabilizer platform, front organizer pocket, and padded shoulder straps.
