If you order by two or three in the afternoon, Uline will usually have it at your door the next day with regular ground shipping. You can't beat that, and it's about as close to spur of the moment as you can get.
If you want to spur of the moment and only want one or two of them, UPS stores carry the UPS box, same size, with the UPS logo on it (and a larger size one too).
