So, I walked into Office Depot the other day, and I wanted one of those grounding power adaptors for my laptop. When I was passing the GPS department, I saw all of them had markdowns (except for this one with a HUGE screen), and I was lucky to find this:
TomTom XL 350 GPS with lifetime traffic+maps for $74.92 (original price was $149.99). SKU: 478023
This is just an example, but walk into your B&M OfficeDepot and pick one up. Many of them are on sale, and just in case this might be a YMMV, I am in the Washington, DC area.
