The website is in desperate need of an update. Poor filtering, which requires endless scrolling to find things. They assume that shipping and billing are different, so if you miss the check box you have to fill it all out twice. My order wouldn't go through - it twirled and twirled without moving for about 5 minutes so I called and after another 5 minutes on hold, the agent told me the problem was on my end.
Funny, I didn't have a problem when I went to Amazon next.
