Leapfrog have 1/3 off Tag and Tag Junior products at various retailers.
I must admit that I see a lot of 'fads' coming and going because of my work, but one of my favourites is still the Leapfrog Tag Junior my daughter received a couple of years ago now. Of course the books and things do add up, so a 1/3rd off is not to be scoffed at!
The offer isn't only for books - they've also included maps, which is great!
So at, for example, The Entertainer, the Leapfrog books start at £6.67, as they do at ELC. The LeapFrog Tag Interactive World Map there is also reduced to £10.04.
If you have a healthy collection, this is a good way to add to it.
