How to check same string value for multiple properties and shorthand if statement?

Basically if any of the value in mailPrice contain N/A or 'n/a` trying to return true its not happening looks like i am missing something , Also if there is any better approach instead of writing big if condition i would appreciate ?

main.js

const drug = {
  "isBrand": false,
  "drugName": "Hydr",
  "drugStrength": "5mg-300mg",
  "drugForm": "Tablet",
  "mailPrice": {
    "costEmployer": "0.0",
    "costToday": "N/A",
    "deductible": "n/a",
    "memberCopayAmount": "0.00",
    "penalties": "N/A",
    "totalDrugCost": "0.00"
  }
}

const priceFilterHandler = (item) => {
  let bRet = false;
  if (item.mailPrice.costEmployer === "N/A" || item.mailPrice.costEmployer === "n/a" || item.mailPrice.costToday == "N/A" || item.mailPrice.costToday === "n/a" || item.mailPrice.penalties === "N/A" || item.mailPrice.penalties === "n/a" || item.mailPrice.deductible === "N/A" || item.mailPrice.deductible === "n/a") {
    bRet = true;
  }

  return bRet;
};

console.log(priceFilterHandler(drug));
