This is a pretty good alarm system. Read a lot of the reviews.
Normally the alarm alone is £149.99 and the Annual Plus Membership is £59.99 (Total £209.98).
But there is an Easter deal on the alarm, knocking down to 99.99 and if you add the plus service and use the coupon code PHONE25 you can get £25 off the annual plus membership.
