現金で支払うことが多いって英語でなんて言うの？

A 'method of payment' includes all forms: cash, credit cards, Paypal, finance, personal loans, mortgage etc. Different products may have different methods of payment available.

Cash and card are the most common payment methods. When we pay with a credit card or debit card, we usually just refer to it as "paying by card".

This is a way to state informally in American English that regardless of what you are buying or where you are, most of the time you are paying with cash and not with a card or a different method of payment. I hope this helps :)

"Cash is king" is a common expression to say that cash is the best method of payment for goods and services. Alternatively, you can explain that you don't carry bank/credit cards with you, so cash is the only way which you can pay for something. Both of these sentences are acceptable for everyday use.

If you do something alot of the time but not all the time then you can say 'usually' or 'most of the time' You can use in/with to describe paying money
