Sainsburys have the 4 pack of the above toilet rolls at £1.32, which itself is ok.
What is even better, is if you are satisfied with the product, you can send it off for money off coupons back. The packaging says 4 x £1 coupons - which is obviously more than double, so dont know if the coupons back would be two lots of 'up to £2' - even so, it works out at a further 8 toilet rolls for the price of the stamp to send away til receipt.!
Alternatively, if you are not satisfied, you can send til receipt back for full refund. I cant see to many HUKD folks doing that.
