Went into Tesco's Bosham yesterday where they were selling the Russian Standard 1 Litre for £10....good price....only thing is they charged me £18.62!!
Went up to Customer Service who gave me double the difference back!
So, I got 8.62 x2 = £17.24
Off the original £18.62 = £1.38
Asked at the time if this was open to anyone....they said only to those they don't recognice...so encourgaed 2 mates with me to go up and buy straight away!!
