Walmart.com rolls back the price of the Garmin Nuvi 1100LM GPS from $129.99 to $89, the lowest price we've ever seen for a Garmin with lifetime maps. It features a 3.5" display with backlighting for a clear view even on a very sunny day. The map updates mean you can download the newest maps up to 4x a month, so you always know where constructions zones pop up. In-store pickup is free; otherwise shipping adds $0.97. Most states charge tax.
