As per GoodGym instructions, I called Ms. S before arriving at the shops to get her shopping list, which took longer than the shop as she was thinking of what to get. She had an assortment of items from all various aisles, which made the shop more interesting with the aspects of it being more like a treasure hunt!

Got all the items and it came just over the £20 mark (£20.44), but this shouldn't be an issue.
