I know this thread is a bit old but whenever I googled how to change the staples address I kept coming across this thread. I finally have an answer and thought I'd forward it. When you call the LDS distribution center to have your new Bishop's address changed it should send the updated address to Staples. However, Staples often needs to manually change the account to the new address. To contact them call (877-295-0003 Mon-Fri 6AM-6PM MST) or just in case that phone number changes go to
Log into 'store.lds.org' go to 'unit materials'. The bottom of that page shows something like:
For orders to the United States:
