Walmart offers the TomTom START 50M 5" Portable GPS with Lifetime Maps for $59.98 plus $2.97 for shipping. (You can also choose free Site-to-Store.) That's $27 under the lowest total price we could find for a similar model without lifetime maps, although we saw it for a buck less last week. Sales tax is added where applicable. It features a 5" display, lane assist, maps of the U.S., roadside assistance, and more.
