Oh wait, I forgot something. I was only listing the options for when I want the game to be delivered to my house and that is either paying upfront or cash on delivery. There is always the option to pre-order something online and then go to the store yourself to pick it up and pay for it there. But going to the store is sometimes more expensive than having it delivered by courier. It depends on exactly where you live, how far is the closest store, etc.
Yeah, I am in the Eurozone, that is why I complain about the fact that new games on Steam / Origin go for 60 EUR, instead of the usual 60 USD. But retail pricing is a bit different - probably based on the dollar (from a while back when it was way cheaper) and retailers are also reluctant to increasing the prices, since price is the main reason games don't sell really well here.
Well, that only goes for smaller companies. The big ones don't do stuff like this, they invest heavily in DRMs, so there is no need for them to add weird things into the game as well. They fail to realize that their protection will get cracked (unless it is an always online DRM with computing stuff on distant servers). You can get a pretty accurate picture from pirated AAA games, when day 1 patch is included.
I was actually talking about getting it delivered from the Gamestop website, I haven't stepped instead a game shop on a regular bases since Game closed down in Ireland. I don't like how Gamestop is laid out and there staff aren't as helpful as the staff in Game used to be.
The awesome thing about Gamestop.ie is that they have a warehouse in Ireland, so the shipping is not as expensive as it is when I have to order from the UK and I get it the day of or the day before release.
I misunderstood what you meant by retail price - I thought you meant digital v retail in your own country not versus USD. 
I have that problem with most things, the digital prices on iTunes & the Kindle Store are ridiculous, but I don't mind 60EUR - 70EUR for a game, that is pretty much the price I've always paid.
The only company I know that gives people in the Eurozone, USD comparable prices is Comixology - 2.50EUR for a comic is kickass in comparison to 5 for a physical copy. Even though they are an Amazon company they've kept those prices.
RockSteady put in that thing with Batman's glide ability in their games, but yes it is mostly smaller studios that do that.
