If nobody got a discount I would say: Okay just decide if it's worth for you or not.
But giving a discount to people on another plattform who didn't buy on day one is just unfair!
I bought ME3 N7 collectors Edition and all the dlc on Origin: No discount for me!
Other people bought just ME3 on Steam: 17% Discount.
If it is your policy to give advantages to people who prefer Steam over Origin and wait for baragins then fine no problem for me.
Now I know where to buy! I will just wait till the ME3 Special Edition is reduced on Steam in a few months. (If I'm still interested then)
Big part of me thinks it's Steam giving the discount out if their own pocket. EA are thinking they'll get full price per unit but Steam are willing to take a slight hit to make sure as many units as possible are sold through them...They're setting up to kill Origin...Either that or EA are just mean, dumb people....
It is Valve's shop, so it is of course Valves decision to grant the discount.
The point many are missing is that Mass Effect 3 is only available for less than a year on Steam.
So it is a discount for people that only very recently brought the game.
