A couple great deals I found on slickdeals:
Use coupon code Welcome123f for $10 off bringing the total to $60
The TomTom website is selling the TomTom GO LIVE Top Gear Edition GPS for $70 (marked down from $269.95). This is "special edition" endorsed by Jeremy Clarkson, host of Top Gear (a BBC car show).
Lots of other GPSs on sale that you can use the code for, too. TomToms aren't as reliable as Garmin, but I needed one and I'm a huge fan of Top Gear. Others are as low...
