In addition to the fact that CSS Partner must offer you space to display your products on their price comparison site, you can get a discount of up to 20% from the regular cost per click on Google Shopping or P. Max Ads.
Example:
If you are paying 1.00€ for a click now, thanks to CSS Partner you can in certain cases have a price of only around 0.80€ per click. This means that you can either reduce your overall budget or what is more recommended, keep it as you have and you will have more clicks and get more traffic to your e-shop.
