I added product A and Product B  and i get 140+140 = 280$.. but i want when i added 2 product to get new price.. like this.. 

A+B = $140 + $140 = 240$

All next products same result like this A+B+C = 140+140+140 = 340$ and etc.

You can setup Cart Total price rule from the back office, but not randomly applied price! (I experienced this same requirement like, Jet.com)

You can do it with these 2 modules:

- If you want to apply the discount as a cart rule https://addons.prestashop.com/en/promotions-gifts/9129-promotions-and-discounts-3x2-sales-offers-packs.html

- If you want to apply the discount as a specific price https://addons.prestashop.com/en/promotions-gifts/7422-price-increment-reduction-by-group-category-and-more.html
