After registering my new address on MyMove.com [mymove.com]
(click "Change of Address"), I received an offer for 15% off my next $1,000 spent on items sold by Amazon.com. You can use the promotional code multiple times until you reach $1,000 in purchases ($150 off max). My code expires on Dec 23, but I think the expiration will always be ~10 days after you receive the code. It took about an hour after registering before I received my promotional code via e-mail.
Here are the terms and conditions as stated in the email:
