What are these numbers? This list was found by Steve and he thinks they could be a running total of the prices.
What else do we know? This list was taken from a spiral bound notepad which has been cut vertically. The list was written by more that one person, compare BLACK BAGS with Bananas, not only capitalisation but also a difference in the Bs.
This person is a crosser offer. They have bought no meat, a vegetarian? Actually there is some ham near the end.
The addition of the newspaper on the list suggest a weekly newspaper rather than a daily. This fits as Steve found the list on a Sunday
