I heard that it's a convenience to the guests to give them several options. I don't have to think about registering for awhile yet, but I would feel gift-grabby/rude registering at 3 stores! We are in our early twenties and don't have much (and what we do have isn't of quality to last), so most everyone I've talked to thinks I'm being silly. What's standard? What's rude? Where's the line?
ETA: I saw someone asked this question recently, so nevermind! I'm one of the first among my friends to get married, which is why I'm so clueless about everything! =/
