Regularly $14.99 but free today if you have an Android Phone from the Amazon Apps Store.
I’m not sure if I will need it, but might as well download it to have it, and I can always delete it later if necessary.
Appstore occupies 2.59MB and can be moved to your SD card (at least on my Cyanogen rooted Droid).
OfficeSuite occupies 13.07MB and can also be moved to the SD card.
