Large wd40 spray can half price Tesco petrol station
Its fish oil.
I heard a rumour that WD40 has never been patented so they don't have to release what the product is made up of to prevent rival companies creating a similar cheaper product. If anyone has a Halford's trade card you can get massive discounts on WD40 there.
Looks like two left on the shelf, not a few.
Also in Cardiff gabalfa, was loads left yesterday evening
