Tickets are one of the easiest, most fantastic last minute gifting options. Spend 10 minutes online finding a show or event you know she would want to go to, and then simply print out the tickets. The greatest part is it doesn't seem like a last minute gift. It could have just as easily been something you planned all along. Remember when you are choosing something that you're going to have to go as well, so while you should try to pick something she'll love, it's probably a decent idea to pick something you won't actively hate.
