Penguinbait:
- You paid an amount X in dollars that was equivalent to an amount Y pounds at the time.
- You got refunded Y pounds, to a new exchange rate, amounting to Z dollars.
- When you re-order, you will have to pay that exact same Y pounds that you originally paid, and which you got refunded.
- To pay those Y pounds you now only have to pay Z dollars.

In other words, unless the exchange rate fluctuates a lot between you receiving the refund and you re-ordering you'll end up with losing whatever extra charges you had to pay at the time of the original ordering (and whatever charges you have to pay now). You _don't_ lose due to the exchange rate changes: The pound dropped compared to the dollar. You got less dollars back, but there are less dollars to pay, for the same reason.

Now, if that CC re-order link could just get ready.. apparently it depends on those final refunds reaching some US customers. It's all in the hands of that darn bank, apparently.
