Savings returned are not present in product's page

I'm using this library connecting to the 'IT' region, using standard AWS credentials (id, secret and tag).

Some of the products returned contain a 'ghost' saving that's not shown in Amazon's page.

Let's take for example this product:

https://www.amazon.it/dp/B07WP5RDM2?tag=sshopping-21&linkCode=osi&th=1&psc=1

                          'price': {'amount': 9.99,
                                    'currency': 'EUR',
                                    'display_amount': '9,99\xa0€',
                                    'price_per_unit': None,
                                    'savings': {'amount': 20.0,
                                                'currency': 'EUR',
                                                'display_amount': '20,00\xa0€ '
                                                                  '(67%)',
                                                'percentage': 67,
                                                'price_per_unit': None}},

The full price should be 29.99, with a discount of 67%. In reality 9.99 is the full price shown and no discount is reported.

The code I'm using to recover this product is: results = client.search_items( item_count=10, item_page=1, keywords="ELEFULL 10000mAh Power Bank Caricatore Portatile,2 USB Batteria Esterna con LED Digitale Display per Telefoni Moible, Tablet e Altro" )

I've uploaded the full output for convenience: https://gist.github.com/aegroto/e0ed6b85ce0f70add503584e49605b60

To check is a product is in discount you have to use the property isDiscount. If true, the original price is available at originalPrice.display_amount and the discounted price is available at bestOffer.price.display_amount. Otherwise the bestOffer.price.display_amount property is the price which is equal to the originalPrice.display_amount.
