The 'order more' button seems not to be working.  In the past, it would simply add the additional books to your first order when you clicked the 'add' button.  Today it is giving me a new window to check the address, as if another book hasn't been ordered.

Maybe they're working on the site again, because I encountered a weird glitch yesterday. The WL book I received wasn't removed from my WL, even though it was marked received in good condition. It still showed 1 wisher. When I went and manually removed it from my WL, it showed 0 wishers. It wasn't an alternate version either. It was the exact book I had received. Weird.
