Big sale going on at indie Gala Store right now (or so says the e-mail i got) https://store.indiegala.com/index.php/

most things are at huge discounts.

Are these Steam redeemable?
I know it says 'Steam client required', but I'm curious if anyone tried it and if they are actually redeemable. Although I'm unable to purchase anything from Amazon, that is a very nice deal.

Short answer : yes .

The THQ and EA coupons work the 25th, the 2K coupon will work on the 26th

"Steam client required" means "Steam client required", man. Why so paranoid?

What is the long answer?

yyyyyyyyyyyyyyyyyyyyyyyyyyyyyeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeesssssssssssssssssssssssssssssss

My life has left me a not very trusting person.
Still, like I said I can't buy anything from Amazon so I was just curious because it seemed too good to be true.

Amazon has superb customer service. Anything they have as a requirement is generally true and in the rare rare rare chance something turns out not to be true, they will get you a refund easily.
As for not being able to buy from netherlands, there's plenty of threads around where people outside the US have purchased these games just by using a fake US address since the games are digitally received and not shipped.

Without a creditcard?

How is blades of time? anyone care to share their experience? also is it steam activated (the amazon one)

Well, you'll need some form of online payment. I've always used a CC so not sure what their other options are if any. I didn't know your restriction was no credit card. Thought it was more to do with Amazon "restricting" those gaming deals to US addresses.

I have seen some reviews > should be just average...

Use a fake address, everyone does, the Steam key games are damned easy.

Amazon has a lot of payment options, I think you can even use Paypal, Google Checkout, or whatnot if you need. You might need to check, I'm kind of guessing because I use the easiest shit for me, which is a debit card.
