ON line they are £299 but I saw one today in my local JL for £275. They are the old model which they are selling off before the plus is in stock.
Just thought someone might be interested.
The saleswoman told me though that the new one was sturdier, seat wider BUT you have to pay separately for the hood and this knocks the price up to nearer £500 - gulp.
Anyway thought I would post as £299 still seems a bargain.
