Good stuff this and with 40p off normal price. Found this at the Tesco store on the Isle of Wight a few days ago.
I would however recommend the Tesco version as it's a lot cheaper and I find it works better, that bargain can be found here:http://www.hotukdeals.com/item/525068/tesco-ultra-power-toilet-cleaner-75
But if you'd rather have the branded stuff then I'm sure this post will be of help to you. Comes in original and citrous scents.
