Where could I find merch for...?

I'm a huge Hilary Duff fan, and I'm always looking to find t-shirts,dolls,DVDs and other merchandise of hers. In the past years its been increasing harder to find. I know you can buy a lot of stuff on ebay but, I don't have a credit card and they don't accept visa gift cards.I've also tried her website to no success. So, if anyone knows where I might be able to find some merch, it'd be much appreciated.
