I read their comment differently than you did. I think the point they are making about exchange rates goes like this:

The dollar amount in CAD was normally higher than the equivalent in USD. For example, next to the bar code on the back of a paperback, it would list the prices as $15 USD or $20 CAD. Many other goods have similar price differences.

Lately in the US it seems like a lot of prices are increasing to the same number value, despite the exchange rate.
