Finally, a real bang for your buck.

Naughty America is offering access to its dozens of online porn sites in exchange for your unused gift cards. That means you can turn in that Barnes & Noble gift card -- come on, you weren't going to use it anyway -- and get "more than 5,000 porn videos and 2,000 porn stars, including popular models such as Lisa Ann, Nikki Benz, Julia Ann, Phoenix Marie, Tasha Reign, Brandi Love and Emma Starr," according to Naughty America founder Andreas Hronopoulos.

Plus, the list of gift cards on the safe-for-work exchange site is long and distinguished. Best Buy, Adidas, Cabela's, Petco and Walmart are just a few of the dozens of businesses you can snub for the spank bank. iTunes isn't one of them.

It's all anonymous, so you don't have to tell Grandma that you spent your Starbucks on a different kind of pick-me-up.

"Nothing says America like the freedom of choice," Hronopoulos said. "This is a great deal for the holidays. Instead of using a gift card for a $5 coffee, you're getting a porn subscription."

For reference, $25 will get you 24 days of access to Naughty America properties. $50 gets you 48 days, and $200 gets you 612 days. You don't have to use a credit card or your name, just an email address. A third-party site pays Naughty America for the gift card numbers.
