When the purchase is complete, return to the original window. It will refresh.

From the opening

Nominal figures are measured in current money, the unit printed on the currency. Real figures are measured in purchasing power, which means the money amount has been adjusted by a price index so that it refers to baskets of goods rather than to slips of cash. The opening covers nominal counts current money, real counts baskets of goods, and an index does the translation.

The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
