Where can I buy dramamine bracelets?

My girlfriend gets motion sickness on some theme park rides and has requested I get some of these bracelets for her. I've looked for a bit and can find nothing but the pills. I've seen that there are the pills, patches and the bracelets, her favorite, but I can't seem to find out where to purchase them. I'd rather buy in person than online but will buy from a reputable site, or one that is connected to a well known chain of stores.
