Saw this yesterday but only just had chance to post. It says deal ends 14/02/11 so got to be quick but this a steal. Bought a couple more today.
Not the only thing half price either. Pretty much all valentines food range is:
Best fish pie half price = £1.99
Potato Gratin = £0.75
2 x steaks = £3.49
Vegetable Medley (brocolli, green beans & peas) = £0.75
There were more deals but can't remember them off the top of my head!
