First set £7.99 · Free UK delivery over £25
Four products. No filler, no fifteen variants of the same thing. Start with the set and refill it from there.
Buy the bottle once and keep it. From then on you are buying pouches: the same 500ml of gel, in packaging that uses a fraction of the plastic.
It is the reason the Duo is the set most people start with. You get the bottle and your first refill together, at the first-order price.
