Without commenting on the correctness of the English in the article, which I didn't finish reading: when I moved to the US as a Brit, I was amused by many commercials' use of "a savings" to describe the effect of a sale or discount (e.g. "a 20% Savings!")

In this case, the collective noun "savings" is used with the singular article "a". This one shows up in both spoken and written American English.

Obviously, I can point intellectually to how and why it's correct, but it still sounds somehow weird and a bit folksy to this immigrant :)
