For the type of wedding we're having, we don't need the traditional invitation set up. I've been looking around for any low-cost, simple invites and I found ones the fiance and I BOTH love.. They're greeting cards from Costco that I was able customize.. Only issue.. there's no response card to send out.. Do I spend some more money/time on creating ones to include or just have the RSVP info in the invite? These cards are COMPLETELY customizable..
