BUT - they aren't advertising it. They're clearing old stock, and don't want to many people to know about it.
They may have a small shelf edge label on them, or they could still be priced up at full price - just ask a member of staff to check the price at the checkout, and bobs your uncle!
Not all the stores will have them, and they have VERY little stock.
(for those who live close to a store, most open till 8, and some till 9 or 10)
