Holy batman, what is the meaning of this???

My husband and I are traveling to Italy in about a month (eek), and beyond a financial windfall, we also need some good city maps for our adventures. So late last week, I hopped on Tripadvisor.com to do some research, deciding on the Rough Guide Maps... great reviews, waterproof, awesome.

So I ordered one for Rome, Florence, Venice.

Perfect.

Or so I thought. I received a puzzling note about how two shipped, and I thought, hm wonder when the other will. Check it out.

Seriously?? Amazon, you kill me with your free-but-entirely-crappy shipping.
