Your network stores are interested in selling you the contract, which of course is the way mobile carriers make a profit, your monthly bill. But they will not generally unlock a phone for you. However if you have already purchased a phone, you can tell them your "traveling overseas" and need to use an international SIM, most times, they will then give you the unlock code.

The best place to begin your search for an unlocked smartphone is the internet. First try Craigslist. It's local, and you may find a great deal without having to wait for shipping.
Tips for Craigslist: Never send money. Only complete face to face transactions.Only meet in a public place, and always bring a friend.

Next look at eBay. This is the ultimate market place for cell phones. Simply search "unlock" and the model of phone you're looking for.
Tips for eBay: ALWAYS check the sellers feedback. Use a credit card when shopping for added protection against fraud. Be sure your shipping includes tracking and insurance.

Finally, if you end up purchasing a phone from your carrier, you can get it unlocked your self by calling your network as stated above, or look on the internet by searching "unlock codes" followed by your specific phone model.
