If ever you need six copies of Eat, Pray, Love, and don't want to pay ~$120 for them, look no further than Value Village. It's their most popular novel, which surely means it's the one people loved the most. People loved it so much, they wanted to pass the burden joy onto someone else!
If you're really feeling like splurging, you could also buy up all seventeen copies of 2002's masterpiece drama, Spiderman. Or even the nine copies of its 2004 sequel!
