I have no fricken clue. I want to register at one store and one of the sites that goes for honeymoon and down payment on a new place. Those are mainly what I want... but I could always use a new pots and pan set. Haha.
We did Bed Bath and Beyond, Crate and Barrel and Amazon. That way, we had things in all prices at all the stores. Most importantly, Amazon's "Universal Wish List" was a great "catch all" for all of the miscellaneous things (artwork, vacuum, etc.)
We did Bed Bath & Beyond, Amazon.com, and Home Depot. FH's house was built in the 1920's and needs work. Plus, he thought it was fun to register for stuff that only he will use. He wasn't nearly as excited about the dishes as I was.
