Keep in mind that even though it is 0% interest, they apply any payments you make on your account to the promotional amount first, so you will be accumulating interest on your other charges while your 0% balance gets paid off. So unless you have no balance when you charge the package, and don't charge anything else, there's really not much advantage to the 0% interest. I had this happen to me a long time ago on another card, so I asked Disney Visa if this is the way it would work on this promotion and they told me yes, that's the way it is handled. Be wary!
