Some good value car care stuff in Lidls at the moment. Model specific pairs of Windscreen wipers, £2.99/pair (got 2 pairs 530/480mm for my Marea), Halogen headlamp bulbs H1 (blue) and H4, £2.99/pair, 5 litre windscreen wash concentrate £3.99, etc (and their 15x40 SJ rated motor oil seems good value too).
