I have a few times, very very easy. Probably the easiest way to deposit is to find a bitcoin ATM - not sure if you live in Omaha (I don't) but it appears there is at least one here...

Basically you will pay 7% over market rate for your bitcoins, but it is instant. If you are looking to deposit with a book, just deposit with the book directly (forget depositing to an exchange, then moving the bitcoins to a book, just a wasteful step).
Goes like this...
1. Sign up with book, get deposit address or QR scan
2. Go to Bitcoin ATM with $$$
3. Enter your address or your QR scan
4. Deposit money, bitcoins will be sent to your address in book within 30 mins, probably much sooner
A little intimidating at first, but once you go through it, it's a breeze.
There are other ways to deposit of course, but this is pretty much the easiest and fastest.
