I agree that your gift should not depend on how much it cost the couple. We had about 100 guests at our wedding and I would say the average gift we received was between $100 and $150 (closer family and friends gave more).For weddings we’ve attended we give at $100 (generally if one of us was in the wedding)or more depending on how close we are to the couple. agree that your gift should not depend on how much it cost the couple.
