David Fiske A subtle blend of affiliate marketing and web development

I've just updated Compare Sat Nav and thought I would give a bit more publicity to a TomTom offer - 20% off map updates until the end of July.
 
This week I thought I would take a look at some of the price tracking graphs. They have been recording the lowest prices found since March and now are starting to show some interesting trends.

Nearly £100 has been slashed from the Becker Traffic Assist 7934 TMC.

Nearly £130 has been added onto the Blaupunkt Luuca MP3 in the last week.

The Garmin Nuvi 310 experienced a £40 blip, forming a "tent" graph!

What's quite interesting is that the nation's favourite system (according to me!) - the Navman F20 - has a relatively stable trend.

Another very interesting graph is the TomTom Go 910 - if you bought it back in June, you got a bargain!

These price changes are more than likely due to a change in the cheapest retailer rather than one retailer putting up / lowering their prices. The graphs should be very useful around Christmas to determine the real deals!
