A: You can register for more items than invitees, especially if you're listed at several stores—you want to provide options at various price points. Peri Wolfman, vice president of product design at Williams-Sonoma, suggests that you include one gift per shower attendee, priced between $30 and $50, and at least one gift per couple invited to the wedding, between $75 and $150. (Throw in a few items under $25, too.) Include several objects that aren't part of a set, such as a standing mixer, coffee pot or a pair of candlesticks. And consider big-ticket items for guests who want to pool their resources: Luggage, furniture, electronics, even camping equipment make great group gifts.
