Well now, isn't that interesting.

My old order, still due in October, was $56.99 in all. I've just placed a new order on the item above, for a grand total of $63.11, including $17 postage from the US.

I figured it might have been another bit of Amazon bullshit, but no, when I check on Amazon US they actually have stock. And also had I purchased directly from Amazon US it would have cost $93...

We'll see how it turns out - normally placing an order results in an instant charge to my credit card, but I don't see that yet.
