Just been into the Cannock Sainsbury store and found big (around 2lb in weight) tubs of mincemeat for 10p each. The use by date November 2013 so worthwhile stocking up for this year and next. Use it in mincepies then freeze them for next year. To be honest the mincemeat should be ok anyway after the use by if it's kept cool.
I have put that this is local but it may be in other stores too.
