Update: This has been solved.

I have a few apps from the Amazon App store that downloaded and for whatever reason couldn't complete installing on my phone (An LG Optimus V). When I go to My Apps, it shows them as ready to install, so I'm guessing the apk or whatever is hanging out on my phone somewhere taking up space. How do I remove these without uninstall?
I am rooted, have SU, Root explorer and Titanium Backup.
Thanks

\sdcard\Android\Data\com.amazon.venezia\cache any file starting with vnz is safe to delete.Amazon said:We currently do not have a method of removing downloaded app files from within the Appstore itself, but you can remove them by connecting your phone to your computer.
To remove the downloaded files from your phone, connect to your computer, then open the SD card. Open the "Android" folder, then "Data", then "com.amazon.venezia", then "cache". If you've purchased any apps from the Appstore, but haven't installed them yet, you'll see them listed here. These files are automatically deleted when you install them, but you can manually delete them from your computer as well. The file names will start with "vnz". Deleting any other files from your device could cause problems, and is not recommended.
We currently do not have a feature enabled to remove an app you've purchased from your "My Apps" list, but I've made sure our developers are aware that this is a commonly requested feature. We appreciate your feedback.
