As best I can tell, Progressive (yes, the company that has all of those commercials with "Flo") generates $25 billion in annual revenue and spends a bit more than $500 million on marketing.
That's a 2% ad-to-sales ratio.
And they apparently pay "Flo" $500,000 a year ... 1% of their marketing budget. All stats can be identified via Google searches.
There are ways to not spend 25% - 30% of net sales on paper.
