We started chatting about dealing with the inevitable and painful piles of paper. Some good ideas on the early January posts there.
I stuffed all my Xmas gift receipts into one pocket of my purse, handy for the returns. . I then keep them in an envelope in my dresser drawer for one year. I really like the suggestion of having a one year folder, that you dump the old when you get the new.
We keep more than one utility bill in order to track year to year usage but that is probably just being silly. Our bill does show "last year at this month' readings.
