Selection of media ok and everything ok until you want to pay, that's the two stars it's worth. But then, when you want to check out, whether with paypal or not, some required buttons are not displayed in all browser versions, so you have to re-try and re-place your order with different browsers and versions again and again, and reload again and again, until at some point, one or the other the buttons appear and you can proceed. Unusable for everyday use. This is my experience not just once, but several times in several months. Why not just use standard, basic html which will work with any client, just like other sites manage to do?
