I was at the ideal home exhibition today and Iwas convinced I needed one of these but they were offering just 20% off.
I did get a coupon though for 15% off a £25 spend using code - IDEALHLHZ7BNMT. You need to enter it at the checkout under the voucher tab.
This brings the price down to £169.99 with instalation and you can get a further 2.6% off via TopCashback.
Hope this helps someone!
