I just got back from getting my refund. I bought my awesome Costco Bionic package deal (http://forums.androidcentral.com/droid-bionic/113925-awesome-costco-deal.html) on launch day and now the phone is $100 cheaper. I read a few posts saying people were getting the difference refunded. I thought it was worth a try, I went back and forth from the kiosk and customer service a couple times but I got my money.
So if you bought it on launch day, you have three more days to get free money!
