Some actions take very little time but need to be done in the right location. As soon as you put the card in your pocket, you can add "login ..." to a list of "things to do when on the computer" or whatever, so you don't need to think about it until you're in the right location.
After I started GTD, I started being amazed that things were already done. Previously things had bugged me over and over again, similar to your forgetting the coupon card. Once I got into GTD, I'd be expecting some irritation and be surprised to find that I'd already fixed something or already put something in the right place, and I almost felt like complaining "hey, no fair, I have nothing left to complain about!" Now I'm used to it, and when something comes up, I find some way to list it where I'll see it at the appropriate time. Lots of things aren't done yet, but it's generally because I haven't had time for them yet, not because I've forgotten to do them or something.
When I'm at home and thinking I'll bring something to work, I put it in my backpack immediately. Then when I leave for work I don't need to think about what to bring.
