A Loot Crate at half off, of course.
What’s a Loot Crate? It’s: 6-8 handpicked items of geeky and/or gamer gear, collectibles, toys, apparel, art, and other goodies. It normally costs about $20/month, but right now they have a 1-month Groupon deal available for just $10.
You will need to remember to cancel your subscription (rather than have it renew automatically) if you don’t want more than a month, but still, $10 for 6-8 fun, exclusive items sounds like a deal to me.
