Grocery stores are storing information about my purchases so that they can have statistics about me and everyone else on what sells and what does not. They know who I am because of my "price savings" card. Why not mail me a yearly statement of what I have bought. (I have a credit card that does this
for me.)
Better yet, send me the data electronically so I can do my own data mining on myself. Data should include Item, number purchased, total spent, and maybe a catagory that classifies similar items together. No need to report every single transaction, just the totals I think.
They have the data, I think the least they could do is let us have access to our own records.

You won't believe the statistics some people have compiled from other people's grocery receipts... [Lemon, Aug 16 2000, last modified Oct 04 2004]

I'd be interesting in seeing this, but it's another case of having something classified from the one person who should actually have access... |

That's why we need coordinated efforts at nonproprietary data mining. Nonproprietary anything is theoretically impossible due to the iron law of tragedy of the commons, of course, but people say I'm a dreamer. I wouldn't want to let those people down. |

And here I was picturing something like the stock report, only listing the current price of various staple goods at different stores. |
