What reloadable credit card is the best for a teen?

So i have a job and I am saving my money, and I would like to be able to buy things online via a credit card (my own card, so i wont hassle me mom with it any more). I have seen ads for the american express pass card, but in the past i had a visa gift card thing. I am totally confused and I am just looking for some advice as to what card would be the best for a teen. Thanks!!|||Shop around and read the backs of the cards first to learn their charges so you can make the best decision for you. Often you have to consider fees for the year, month, number of charges, loading, etc. It's pretty confusing so make sure you compare a few. A good place to start would be the Walmart, Meijer, Costco kind of cards. Call a few of the banks or credit unions in your town too. I've heard a lot of people suggest Green Dot though I'm not familiar with it myself. Like anything involving credit, the key is to shop around and compare all the crazy little charges they like to throw at you.|||Green Dot
