My friend eloped with her now-husband a few months ago, and we just received an invitation for their cocktail reception celebration. It's during the late afternoon (3 hours long), and basically cocktails and hors d'oeuvres. I don't know how much $$ we should give them. They gave us a $300 GC for our wedding, but we had a large, formal (expensive) wedding. Should we give the same amount? I don't want to seem tacky but the cocktail reception is going to cost less than 1/10th of our wedding so it seems hardly fair to give the same amount (plus it's a much shorter event). I need help! Thanks!
