Hey ladies! I've been lurking around this board for awhile now, and since I have a question...I figured it was the perfect time to post

We're getting married Oct. 20 in my hometown in Minnesota. I've been checking things off quite quickly in the last month or so, and we're getting to the point now where we will have to wait to do more closer to October.
But anyways! My question... My FI and I had a converstation the other night about giving gifts the day of the wedding to each other, and apparently he has mine already picked out

I've been thinking about it, but I really don't know what I would give him that he already doesn't have, or something that he won't go out and buy before then. (He's SUPER hard to shop for!) Is anyone exchanging gifts the day of? If so, what are you ladies giving your men?
