30% is basically the industry digital standard. Its the same amount Apple and Google take for digital content they sell in their stores.

Once you include retail, packaging and shipping... I guarantee you retail takes a lot more than 30%. Especially when you consider that as the retail price drops... the packaging and shipping costs do not. Whereas that 30% on a digital item does.

they pretty much get 15$ more bucks with steam. also, they dont have to worry about distribution or returns when a game drops in price. they would barely make a profit on 20$ games on retail but would make 14$ when its sold on steam. 

Don't forget tax. Every sale, digital or physical, is subject to sales tax. Here in the UK it's an astronomical 20% of the price of any item (with a few notable exceptions like fruit, milk and biscuits).

so retailers get 15 bucks, i was off by 5 bucks. who gets the returns?

For the love of god or xbox. Do you ever think before you point your fingers at your keyboard? 30% is the standard cut charged by platform holders for digital content including yours truly Master Chief, all portable OS's such as ios, android and windows phone. 

Am curious do you say these kind of things just to get quoted by everyone or are you just ignorant to most things. 

PC isn't my forte as it isn't owned by Sony or MS, so please forgive me in this regard lol. geez u meanie

the consumer, when they return their game  

I was editing out the mean parts but you were too fast. You are repeat offender though. So maybe not so mean hehe. 

30% is the industry standard for all digital sales from all platform holders. Apple set that standard. It was originally thought to be high but it is pretty much standard now.

Thats not  the only thing that referst to. Thats the money publishers spend when they have to return overstocks from retailers. 7bucks is the average but that price probably fluctuates.
