M&S are giving out vouchers that gives you 7e off if you spend 35e or over on food, drink and flowers. Promotion valid from 20th-24th dec.
They gave me a voucher yesterday when I bought a sandwich.
Only 1 voucher per transaction, usual T&Cs.
I can never understand that 1 voucher per transaction, if youre spending 70e for eg., a buyer can just split the shop. Anyway, enjoy...
