Dell Home offers its Dell 17" Tek Laptop Messenger Bag, model no. 8CPGH, for $34.99 with free shipping. That's $20 below list price and tied with our mention from two weeks ago as the best deal we could find. This bag fits laptops with screens up to 17" and features a padded shoulder strap.
Note, Amazon charges the same with free shipping for Prime members, albeit with a three to five week shipping delay.
