I've Got 99 likes and I Just Need 1

My Facebook page is on the verge of 100 likes. This is a pretty cool milestone and I wanted to celebrate it appropriately but I'm at a loss. I figured, I should ask you guys. What should I do once I hit 100 likes to say "Thank you". Should I reduce the price of my e-books? Should I share a previously unpublished short story to my Facebook page? What about a drawing for a free paperback? Let me know in the comments below what you think I should do!
