This is something I should have done long ago! I do so much of my shopping online and every once in a while, I forget about a purchase only to remember it a couple months down the road. This is especially frustrating if I also don't remember where I ordered it from! Oh please, tell me I am not the only one who does this, as I am afriad it may say much about my shopping habits! lol Anyways, I am excited about this printable as it will make organizing my purchases, expected arrival dates and gift purchases easier to track.
If you are not into printables, and only shop online on occasion, another option would be to take a "snip it" of the confirmation screen and store all images in a folder on your desktop (which is what I have been doing up until now) however, it doesn't not include a summary of all of the items purchased and therefore can cause problems if there is a lot of pending orders.
