Not sure what to make of this! Ordered a 2 pack of Redex at £10.45. The advert disappeared and 1 was being sold for the same amount (expensive) . Tried to cancel about 20 min after ordering, seller refused. Item turned up and it was a four pack! So £7 - £8 at Halfords for 500ml, £2.62 ish from
d2paccessories - should keep me going for a long while!
