15 cents a minute by the second is often cheaper than 10 cents a minute rounded to the nearest minute.

Here is the announcement. US to US calls are 17 cents a minute. Half a minute or less was 9 cents.

I am writing to inform you of a change in the way calls on the Tru network are billed.
As of March 28 2012, all calls made from or received in the USA will be billed in increments of one minute.
There are no changes to your rates or service agreement with Tru, and no action is required of you.

Unfortunately, I valued the half minute pricing also.
