Jane es una autora que vende sus libros en Amazon.com. Jane quiere poner en marcha una promoción, pero se da cuenta de que no puede hacerlo. ¿Cuál de las siguientes razones impide que Jane ponga en marcha una promoción?

The correct answer is that books are a restricted category for promotions. Amazon has specific guidelines for promotions, and certain product categories, including books, are often excluded from standard promotional tools due to fixed pricing agreements or other marketplace rules. Therefore, Jane cannot run a promotion because her products fall into this restricted category. The other options are incorrect because Amazon.com does not typically require an invitation for sellers to run promotions; rather, eligibility is based on account standing and product category. Additionally, whether Jane is considered a vendor or a third-party seller does not inherently prevent her from running promotions, as both types of sellers can utilize promotional tools for eligible products.
