Went to Wickes in Reading (Oxford Road) for some washers, and walked past the motoring section and found some bargains.
2 Tonne Bottle Jack £2.44 (http://www.wickes.co.uk/2-Tonne-Bottle-Jack/invt/190386)
2 Tonne Foldable Axle Stands £1.71 (http://www.wickes.co.uk/2-Tonne-Foldable-Axle-Stands/invt/190385)
2 Tonne Trolley Jack £3.66 (http://www.wickes.co.uk/2-Tonne-Light-Duty-Trolley-Jack/invt/190381)
I actually bought the jack a month ago when it was posted here for £8, so this is a real bargain. The jack wasn't in stock in Reading, but the rest were.
I also got a flexible funnel for 24p and a little oil can for 48p. Other things I saw were digital tyre pressure gauge for £1.48 and various oil for less than a fiver.
