My local Tesco has been selling off quality computer related leads and cables over the past week or so - I bought an OfficeEssentials 1.8m standard parallel printer cable with gold plated copper contacts and lifetime warranty (as a spare) for 96p...:-)
The reason is probably because more and more printers come with USB connection.
In similar vein - because people now use different types of car polish - was the purchase of several tins of TripleWax car polish in the round cans. A number of Tesco stores made the offer. Price was 55p..:-)
To my surprise it's not the old hard type, but a semi-paste similar to AugoGlym SuperResin Polish.
Stuartli i did remove it from the tin i put it on a pyrex dish just blew up there was hardly any polish on the pyrex plate it was all on the sides top and bottom of the microwave ! i had to get it all off with a hot air gun that gets paint off took me 3 days to do !
