I think the gift card box we registered for is too small. 8"x8"x7" for 175 guests. We got it at the bridal shower a few months ago. I don't know gift-card-volume-to-guest ratios, so I was just guessing when we registered, and now having actually paid attention at other weddings this summer, I should've definitely asked for a bigger one. I'm close enough with the bridesmaid who gave it to me to tell her and I don't think she'll mind. But certainly it feels rude to not use it, and putting out two card boxes seems greedy. Any advice? Could I turn this one into a decoration by covering the slot and get another box? Do I need to just suck it up and put that small one out and let cards pile up next to it? (I really don't like this idea for security reasons, but if I have to it's our fault for not returning it I guess).
