eBay purchase totals

This script is used for compiling a total of all purchases from My eBay: Purchase history.

It is posted here so we can keep track of it, not for the purpose of others to use it.

Disclaimer: I take no responsibility if you use this script. Ebay can change their website and break the script at any time, or I could be adding numbers other than you expect.

function ebayTotals() {
  if (typeof window.itemTotals === "undefined") {
    window.itemTotals = []
  }
  var currentPageTotal = 0
  document.querySelectorAll(".order-r").forEach(function(orderRow) {
    // This will find the first cost label, which is either the "order total" or
    // the item total if it is the only number.
    var costLabel = orderRow.querySelector(".cost-label")
    currentPageTotal += parseInt(costLabel.innerText.replace(/[^\d]/g, ""))
  })
  window.itemTotals.push(currentPageTotal)
  var message = ""
  message += "You have added the totals for "
  message += window.itemTotals.length.toString() + " pages so far:"
  message += "\n"
  message += "\n"
  window.itemTotals.forEach(function(pageTotal, index) {
    message += "page " + (index + 1) + ": "
    message += pageTotal.toString().replace(/(\d+?)(\d{2})$/, "$1.$2")
    message += "\n"
  })
  message += "-----------------------"
  message += "\n"
  message += "Your current total is: "
  message += window.itemTotals
    .reduce((a, e) => a + e)
    .toString()
    .replace(/(\d+?)(\d{2})$/, "$1.$2")
  message += "\n"
  message += "\n"
  message += "Go to the next page and run this script again to continue adding."
  alert(message)
}

Here is is as a bookmarklet:
