Just an FYI I wanted to pass along--Macy's has now implemented a Bridal Registry Rewards program.
If you register w/Macy's (or their affiliates like Rich's-Macy's, Burdine's-Macy's, etc...) and have a Macy's credit card you will get rewards. At Richs'-Macy's they explained it like this: You will get 5% back on any gifts purchased from your registry and 10% back on any purchases you make w/your card (purchases can be on any thing, not necessarily wedding stuff). You will receive your rewards credit as a gift card after your wedding date.
Hope this helps someone. Good Luck!
