Ah, the registry... I'm an old married lady, but I was bridal registry consultant for 3 years at Carsons, so I thought I may be able to help anyone with registry questions. Here are a few things I learned:
1. Keep in mind that your guests want a choice of what to buy you. However many people you are inviting to the shower, put at least double that number of gifts on the registry. And that's gifts in the $40 range. If you have 20 items on your registry and they're all $2 apiece, one guest will clean your registry out! Also remember that some guests believe in giving gifts at the wedding, not cash. So make sure there are extra gifts on the registry for those folks, as well.
2. Register for the future. Maybe you're in a one bedroom apartment now, but put 2 bedroom sets and 2 bathroom sets on the registry. If you get a partial set of both, return the pieces for one set and finish up the other. Also, you may not be a gourmet chef now, but if you're EVER going to want something like a Kitchen Aid stand mixer, now's the time to ask. You'll never convince someone to drop $200-300 on you again! Don't forget, people may go in on a big gift they know you'd like, so don't feel too guilty putting some "dream gifts" on there.
3. Now is the time for seasonal changes in the stores. Don't count on flannel bedding that you pick out now to be in the stores in February when your shower invites go out. If you do want something seasonal, don't be crushed if your guests can't get it. A good store will notifiy you when something in a pattern or grouping gets discontinued. Also, keep an eye on your registry prices. If you see something go clearance and you must have it, snap it up and call it a present to yourself!
4. Be prepared to get duplicates. No matter how good your stores are at taking things off your registry, your guests can be "funny". Some buy the same gift for every girl cousin/sister/grandchild in the family. If they bought your older sis her wok and your cousin her wok, you're getting the wok. If someone already bought it, you're getting it again. Or, I used to hear "I just want to get a gift and be done." Too bad for you if you have 3 blenders already purchased, you're getting a 4th. Or the folks that want to spend a particular amount of money, and just get one gift. If they want to spend $100 on your gift, and you have one $100 item on your registry that was already purchased, you're getting it again. These people used to kill me!
Anywho, I hope all that helps. If you want registry horror stories, I've got 'em! hee hee. Good luck to all the brides registering!
