What do I buy?

A call for help!

I know everyone on oppo is really good at spending other people's money for them, so I figured I'd come to you guys. I'm buying my dad a birthday gift on Amazon, and I'm $8 away from free shipping. So, what should I buy myself?

Current top runners would be the audio cds for either Pure Heroine (Lorde) or Born to Die (Lana Del Rey). Do you have any better ideas?
