Gift memories and experiences instead.
Something my couples tell me all the time is how they can't stand registering for gifts at all the department stores because they just don't need that stuff. They want to let thier families know they'd like gifts that either create memories or decorate their walls with them. Think about it, would you rather have a toaster or a 2 hour adventure with your wife or husband in the sun? These gifts can have so much more meaning to couples because they are gifts that allow them to create or relive the memories they most cherish.
