I'm trying to purchase the nub replacement for my Pandora on Dragonbox.de. When using the Calculate Shipping button it provides me with three options but does not allow me to select any of them; they are not clickable and there is no button beside them. I can click on the Add to Cart button, but that selects the cheapest shipping method as a default. There does not appear to be a way to select either Fedex or UPS. I've tried different versions of Chrome, Internet Explorer and Firefox with no variation in results. Anyone else have this problem?
