I just bought this today from Tesco and thought this was a good deal
Asdas are selling this for £2.75 and Sainsburys for £2.13
Available both instore and online until the 17th March
A bit of info for you:
Cillit Bang Power Cleaner Grime & Lime's formula simply cuts through the toughest problems like soap scum, bathroom grime and rust. It also dissolves rock hard calcium in seconds so even limescale is no match for the power formula. Cillit Bang Power Cleaner Grime & Lime trigger will restore your surfaces to their original shine and it contains a fresh fragrance to leave your home smelling clean and fresh.
Simply spray onto surfaces, leave for up to one minute (but no longer) and wipe away the tough stains. Rinse the surface thoroughly with water after use. Make sure you always test on an inconspicuous area first to ensure compatibility with the surface.
Hope this helps
