Too late now, but probably better not doing adding up monies spent. It just causes irritation/anxiety.

Sort of related, but a couple of years ago I was going through receipts spent on my T160. The last owner but one had kept around 20yrs worth of receipts. The last owner kept his, so I did the same. Thinking I'm being smart, I transferred it all onto an excel spreadsheet, and when I got adding up all the monies I had spent, I quickly realised I had better password protect it or my wife would kick my a$$
