Research Coupon Websites for Amazon Products in Europe

We need to find websites where we can publish our Amazon products and offer customers a discount on Amazon European Markets (Amazon.co.uk, Amazon.de, Amazon.fr, Amazon.it, amazon.es).
We have similar websites we work with for Amazon.com. for example:
https://www.myvipon.com
https://www.snagshout.com

However, we need coupon websites for our products in Europe
Amazon UK - https://www.amazon.co.uk/Accessories-Packaging-Detailed-Landmarks-Travelers/dp/B077CWTKJY
Amazon DE - https://www.amazon.de/Rubbel-Weltkarte-Rubbeln-Rubbelkarte-Geschenk/dp/B077CWTKJY
Amazon FR - https://www.amazon.fr/Carte-Monde-Gratter-Luxe-autocollants/dp/B077CWTKJY
Amazon IT - https://www.amazon.it/Mappa-bandiere-grattare-dellEuropa-Regalo/dp/B077CWTKJY
Amazon ES - https://www.amazon.es/Rascar-Edici%C3%B3n-Deluxe-ciudades-visit%C3%B3/dp/B077CWTKJY

The task is to find websites where is possible to publish our product and offer a discount. we need at least 5 coupon websites for each market
Amazon.co.uk - 5 websites where we can publish our product.
Amazon.de - 5 websites where we can publish our product.
Amazon.fr - 5 websites where we can publish our product.
Amazon.es - 5 websites where we can publish our product.
Amazon.it - 5 websites where we can publish our product.
