Benjamin Franklin? John Ruskin? Thomas B. Lehon? Anonymous?

Question for Quote Investigator: A family of sayings warns about the dangers of selecting products based on price alone. Here are three instances:
(1) The sweetness of low price never equals the bitterness of poor quality
(2) The bitterness of poor quality remains long after the sweetness of low price is forgotten
(3) The bitter taste of poor service remains long after the sweet taste of low price is forgotten.
This saying has been attributed to U.S. statesman Benjamin Franklin and English art critic John Ruskin. However, I have never seen a solid citation, and I have become skeptical. Would you please explore this topic?

The sweetness of low price never equals the bitterness of poor quality.
