Silly question here... how important is it to have "wedding" postage stamps on your invitations? Do people really care about that sorta thing? I have a decent stash of "regular" stamps, if I used those I would probably only need to buy about 20 more stamps. Is it tacky to use those? I know the invitation sets the whole "mood" for the wedding. If you received an invite with a regular stamp would you think, hmmm... there's one detail she over looked! Or would you even care/notice?
