Just been to my local ASDA and they are doing a special offer on their currys. You can choose any two currys you like, 2 portions of rice, 2 mini bhajis and 2 mini naan breads for only £4. I think this is normally about £7. The price of one curry is £2.88 so this is a bit of a bargain.
Sorry but I don't have a photo to put up. If you go to the curry section in ASDA there will be a sign saying the deal.
NOTE: this is instore only.
