In the case of referencing a method of payment, the correct prepositions are “in,” “with” and “by.” You can use all three interchangeably and they all mean the same thing. However, it’s important to understand the difference between these prepositions if you want to have a more nuanced understanding.
Of course, whenever you’re in doubt, it’s nothing to worry about. Seeing as how there aren’t any strict rules or guidelines for using “in,” “with” or “by,” you’ll be safe with any one of these.
The Difference in Meaning between “In,” “With” and “By”
Prepositions are important words in English sentences. They indicate temporal or spatial relationships between different sections of a sentence. Each one carries a different tone when in combination with the verb, “to pay.”
The word “in” suggests an encompassment or something that’s inside. “With” is a conjoining preposition that connotes connection. To reference a means of or indicate being next to something, you use “by.”
There is more of a tendency for native speakers to say pay in cash and pay by credit card.
