I have a student who uses this idiom very often, but I am not sure if the context is correct.
For example he would say " Our price- quality ratio is the best. You won't find a better product on the market."
I looked it up on the Internet and it's mostly used in the wine industry or financial analysis.
Could you use it in the above context or is there a better expression to say that you get great quality for reasonable price?
Thank you in advance!:-)
