For example, if a buyer have chosen 5 chemicals out of 5 different suppliers (other platforms table), that is the cheapest combination excluding shipping charges (only visible once you are in the cart/ or check out screen). At this point, the platform calculates all possible supplier combinations, including shipping charges. Therefore, as you can see in the optimized purchase (orange table), although compounds price is 50€ more expensive, shipping charges is 100 cheaper (since the 3 compounds are sourced from same supplier).
