Was just in Iceland in Stafford, and they had a freezer of reduced Xmas items. Sure it wasn't there on Wednesday when I was last in. Looks like I was late to the party as the freezer was half empty, but I managed to get:
Beef joint £2
Parsnips in cheese 10p
Sprouts with bacon in cheese 10p
Black pudding rossi 10p
Orange carrot baubles 10p
Cheese soufflé 10p
Was also stuffed turkey joints for £2.50 amongst other things. Guessing it will depend what you store still has left over, got tomorrow's Sunday lunch for under a fiver!
