FI and I didn't want to do STDs because of the cost. I've sort of just been giving people verbal notifications, "Hey, save the date, September 10." And a bunch of them have been saying "Oh God I was getting freaked out that I wasn't invited; I hadn't gotten a save-the-date."
I still don't want to do STDs, but someone suggested I do electronic ones. What's the general consensus on these?
