No. In case seller try's to set certain % cut for developers. No matter what price they sell it forward. And making possible discounts go from developeres wallet not theirs.
If you make cookies and sell one pack of cookies for 1€ to my shop, i will pay you 1€ per pack.
After that i can charge from those cookies to consumers whatever i want.
What would you like if afterwards tell you (your flour per cookies cost 0,8€/pack, just to demonstrate) that i decided to give discount from cookies and tell you that i decided to pay only 0,5€/pack to you.
In many cases manufacturers try to "suggest" retail pricing by labelling price into products prior shipping.
So truly it should go developers tells their price and vendors decide how mutch "profit" they want to add into price. And in many cases retail into retail pricing affect manufacturers willingness to set certain price+profit for their product and local competition usually keeps cost reasonable.
