I would like to know what is the meaning of the term store-testing as seen in the commercial ad below.
Is there a verb "to store-test"? What does it mean?
It seems merriam-webster does not have this word "store-test"
It quite simply means testing the flavour of the coffee in the store before buying it, so as to avoid coming home with a coffee that looks good, but really tastes bad. It’s not (as far as I know) a set phrase, but a more generic equivalent of trying on clothes in the store before buying them.
