I'm wondering if this is going to end up being an error but might be worth keeping an eye on. Instore at Aldi from Monday 30th March, whole leg of lamb 2.2kg - 2.8kg for £3.99 (£1.81-£1.43 per kg). Great price if it turns out to be true. Hopefully it's a loss leader to get them some attention this Easter. If you click on the 'Get Deal' button it will take you to the link on their website which shows the offer.
