In Lidl near the wine section you can find now a stand with wine carrier cases. The deal is supposed to be for any 4 wines from a wine cellar. But if you buy any other 4 wines (even the cheapest ones) and have them in a carrier case, it is most likely you will get £4 off any way. I have tried 3 stores now and in one the cashier said to me that it should be only for the wines from the cellar, but when I said that I have been buying them like that in the other stores, he called a manager and the manager let the wines through with a £4 discount and I heard him saying to the cashier that if it scans through then they should sell them.
Maybe I'm just very lucky... give it a try and let us know in the comments!
