  Renders discount text.

  @param {object} prod - The product we're getting discounts for. We use 'prod' to avoid collision with the global 'product' object.
  @param {object} [variant] - The variant we're getting a discount for. If a variant is supplied, that overrides the product and changes the output.
  @param {string} format - The discount format. Format types are listed below.
