I am attending a wedding this weekend and usually I give the gift of cash at a wedding. The last wedding I gave a cash gift at though was my cousins in 2012 (and I gave her $50). The groom is a childhood friend of my FH and I have met them once in the four years we've been together, so choosing out a specific gift to fit their taste seems out of the question. I found their registries on-line by using Google, and they've pretty much been picked over by now too. We are also planning our own wedding which is in 2 months, so we are definitely on a budget. I had a friend recently give someone a $75 check because he went with the "pay for the plate" plus a little extra, but that sounds like such a random amount to me. I know from my own experience that when you invite a guest, it's so much more than just the cost of a plate to have them there, but I'm also not made of money right now (or ever). It's 2015, what really is the appropriate cash gift for a couple? $50, $100, $200?
