Hello there book lovers! There is a website called GetGlue where you can check-in and get book stickers. Once you reach 20 stickers you can get REAL copies of your stickers for free by filling in a form. I only got a batch of stickers because they tend to skip international requests but if you live in U.S.A you have high chances of getting your stickers. Have fun checking-in!
