In my gmail account, I have a folder called "Orders Pending". I put the receipt I receive from the company there and any tracking info. I'll check the tracking to see where its at from time to time and if I have a number of orders, I'll write them down on a piece of scratch paper with the last 4 numbers of the tracking #. Then when I receive it, I'll move the receipt to the "receipt" folder in case I need to go back and check something. I have a folder for downloads also in case I need to go back and download it again. I think this is called "anal" by some folks but it keeps me on track.
