Yes. Note the USD figure.
Did I say that the price is only in BTC? No. What I said is that the price is in BTC as well!The BTC is in brackets because it's converted at a spot price, and not the official price of the invoice (and certainly wouldn't be legally recognised as the real price).
Those are of course your free interpretations... It is laughable that if some data in official document is unofficial if it is in brackets!?Would you show me a screenshot of a similar invoice issued by a US based vendor if you purchased a product priced ONLY in USD with your GBP credit card? I would like to see the GBP price "in brackets"?
Their are ways to save when paying with foreign currency for items priced in USD. The exchange rate fluctuations effect both for the purchase and the refunds.
In this example you will need an Amazon 19.99% CC advertisement when processing payment for items in the cart.
Here is a great example issued by the Government of Canada.

Returning goods purchased outside Canada
If you decide to return merchandise purchased in a foreign currency and get a refund from the merchant, the dollar amount of your refund may be different from the amount of the original transaction on your credit card statement.
The exchange rate fluctuates from day to day, and the exchange rate may be different on the date the refund was processed than on the original transaction date.
