Don't talk yourself out of registering for a fabulous item because you think it's too expensive. The platter and teapot in your china pattern might seem a little steep to you, but one of your guests might want to spoil you on this special occasion. I thought I would never get my sky blue kitchen mixer, but I was pleasantly surprised when a close family friend sent it to me as an early wedding gift!
While you shouldn't limit yourself, keep in mind that it's probably not in your best interests to register for a specialty coffeemaker that costs more than $1,000 or several pieces of expensive furniture. If you want to add a pricey item that you really want, take a chance and add it, but don't be surprised if it's the only remaining item on your registry when you return from the honeymoon.
