Instructions:Yesterday I was handed a leaflet giving £5 off £25 spend at my local M&S store in Hedge End, Southampton over a period of four weeks. The first week of 4 is until 7th November, second from 8th to 14th November and so on until the 28th November.
If you buy their special offers like half price chicken, multisaver quiches and comfort puds, a good saving can be made. Use your Capital One or Abbey credit card for futher 4% or 5% saving.
There are plenty of leaflets, with a picture of an apple pie slice and "celebrate the season" on the front, available so you are not limited to one per week.
I cannot confirm that this is a nationwide offer but there is no indication that this is exclusive to this one particular store.
