My local Homebase is closing and the entire plumbing section has 50% off so I grabbed a few bottles of X100, Fluidmaster stuff, washer kits etc and got to the till and it all went though at more or less full price, the washer kits were £10.98 even though they were £4 with 50% off and the Sentinal was still about £15 so I put most of the stuff back. I couldn't be bothered arguing as the poor cow had lost her job and I was only in there to pick over the dead carcus and I had to get off to a job.
I bet the Fluidmasters were cheaper version.
