Radioshack, fondly now known as The Shack, is offering the TomTom XXL 530S GPS Receiver for an umistakeably good price.  It has a 5-inch touchscreen (huge in terms of GPSes), IQ routes, text to speech, RDS-TMC traffic, QuickGPS fix, spoken street names and too much to mention here.

It costs $149.99 + $0 S&H = $149.99!
