Thanks alot, works great. I modified it to also add the Tax (which is not included in the price in some jurisdictions, e.g. UK)

Can we get this added to the script?

  // Enhancement: Add Tax
  const taxWrap = document.querySelector("div[class*='vat-installment--wrap']");
  const taxElement = document.querySelector("a[class*='vat-installment--item']");
  const [tax] = taxElement?.textContent.includes('tax') ? parse(taxElement?.textContent) : [0];

  ...

  // Add tax to total
  if (price) total.textContent = `Σ ${prefix}${(price * quantity + shipping + tax).toFixed(2)}${suffix}`;
  if ((shipping || quantity > 1) && !total.isConnected) {
    // Insert total after tax element for clarity
    taxWrap ? taxWrap.insertAdjacentElement('afterend', total) : parent.appendChild(total);
  }

Fixed to ensure tax is added to price before multiplying by quantity. Please disregard above.
