Garmin Forerunner 110 ladies GPS watch with Heart Rate Monitor. £67.99 plus postage from Sweatshop. Use code TAKE20 for 20% off the listed price of £84.99. Postage is free if you spend over £100 (after discount). I also got some running capris, and a couple of tops in their sale, for just a fraction over £100. Returns are free with Sweatshop.
Great price for this watch, particularly as it has a Heart Rate Monitor included.
The reviews for this watch on Sweatshop are 2 1/2* based on 3 reviews, however if you search around you will find much more positive reviews anyway. Someone I know has this watch so I'm buying it on recommendation. Apparently it has better features than the newer watches that Garmin has brought out. This model is being discontinued.
