You could just contact the designer and ask:

No need to buy Calendas as you can legally download it for free directly from atipo. It may be different from the Town & Country version though.

Thanks for the link Ryuk, but I wanted to know about the T&C version, it's more elegant to me.

From the T&C website (Info button)

new weights of our typeface calendas –a more refined version for text, bold italic, display and swashes– exclusively for the redesign of the town&country magazine by edward leida.

Thanks for the info, didn't notice that.

But the exclusivity might be time-limited; the usual practice seems to be for the ownership of exclusive fonts to revert back to the designer within 2-5 years.
