It doesn't make any sense to release a boxed version of our products, because you would have to pay for a DVD duplication, a box, shipping and customs fees so, the products will be way more expensive, for no reason. Why wasting a DVD to hold an installer that will only use a small fraction of its size, which takes minutes to download ?
And of course, if we sold a boxed product ourselves, since we use Esellerate to accept payments, they only take CC or PayPal too.
Maybe with "boxed product", you meant something you could buy in a shop, with cash. In that case, it will be even *more* expensive because, in addition to all the other costs, the retailer will have his own mark-up.
So no, we won't release a boxed product, because it doesn't make any sense with the kind of products we do (if our installers were many GBs, perhaps a DVD might have been useful...), because it's cheaper and faster for you to purchase the download version.
Creating a PayPal account is free so, there's no reason you can't create one.
And, you don't need a Credit Card to use PayPal. You can create a free PayPal account, and Wire Transfer enough money for your purchases to PayPal, and then purchase anything (if there's enough money on the balance) using your PayPal balance. A Credit Card is required to use PayPal only if your PayPal balance is not enough to cover the payment.
