Aisle help you because you help me

Mrs P had a parcel for her son to post so the big queue at the Post Office was my first stop. First Class stamp secured, it was off to Co-op with the most organised list I've had. Every item was marked with the aisle I would find it and sometimes even the shelf (here's looking at you, sandwich spread).

Unsurprisingly, I got everything on the list and was back to a very grateful Mrs P in record time.
