About Verizon unlocked iPhone 5

I want to buy the unlocked iPhone 5…
• Can I just go on a Verizon store and buy it?
• Do I need to sign any contract with Verizon?

The way apple distributes the stock is kind of weird. They keep 70% of their products for actual apple retail stores & the other 30% goes to all of the other places such as at&t, sprint, verizon, radio shack, best buy, etc.at&t & verizon phones sell out the fastest & they are virtually impossible to get a hold of at the carrier stores. Your best bet is to go on to apple.com after 10 pm & after you enter all the information it asks you'll get to a page where it asks for it to be shipped or in-store pickup. When you select in-store pickup you chose your apple retail store & it'll tell you if they are in stock & if they are you can pick it up the next day.that's what i did & it worked perfectly. Also you need to sign a contract for the 2 year upgrade.
