Hm, it worked for me yesterday. Maybe they have already "run out" of coupons? :/

I tried adding it on paypal got this:

Thanks you for being a loyal customer. Unfortunately, you can't save any more offers for this merchant at the moment.

In the terms and conditions it states:

You must add the Offer to your PayPal account before you can receive the discount.

So does that mean I can't get it or will just paying with paypal give me the deal?

It probably means they are already out of vouchers to redeem - so no discount for you or me.

Probably for the best, I'll end up spending less ;)

well, all I can say that I posted only after trying it myself and it worked. topped off my steam wallet with 25€ and only 20€ were taken from my paypal account. So far so good.
Now they can't change what I buy with that steam wallet money so of course I can use it with other discounts in the sense that I can use it to buy stuff in the steam sale.

Also there's no way for them to take back the money, the credit get's used when you pay something on steam for at least 20€ (such as a steam game or wallet topup) and if you get the 5€ credit then it's fine and if not then it didn't work because of the 18k uses limit. but you see that before the actual purchase so it's all fine. no taking back money later or anything.

Lastly I don't find it scummy that they limit it to 18.000 uses of the coupon, because 18.000*5€ is 90.000 so almost one hundred thousand euro. I guess they have to limit the uses to not go bankrupt over the deal ;)

might be they're all out, but I'd try and add one of the other links. People on steamgifts have said that some offers from other countries have worked for them. Anyway, yesterday it still worked, I really don't know about now.

Can't enter the site! It's really very typical that one cannot enter the Steam site in the first hours of the sale: "An error occurred while processing your request."

You misunderstood; I think it's fine to limit the number of coupons, but it sounded like they'd give out unlimited coupons that will stop working after enough people have used them, and people might not even notice it in time, making sure to spend 20 EUR but not getting the credit anymore. That's what I called "scummy", as it seemed like they were counting on people spending huge sums on Steam with hopes of getting credit that they might not get after all. But I didn't consider that you can just revoke the automatical authorization for Steam on PayPal so that you'll have to confirm your purchase on PayPal and then you'd see if the coupon is used or not before going ahead with the transaction.

I managed to do it just as you did, to be on the safe side, even though I usually don't use the Steam wallet in that way. Not sure yet if it was worth it, as so far the deals are rather underwhelming, but the good thing is that the money stays in the wallet even after the sale has ended. :)

My entire wishlist just lit up :P
I went in there to snag one $1 game but it's quickly getting ugly.

Oh yeah, the Steam Sale is here.

*No discount for Vanquish*

Boo. =/

Might get Hitman (2016) after playing the demo, but other than that I don't really have any interest in buying anything else.

It is and its already looking like the GOG sale was significantly better.
I am looking to pick it up as well after playing the demo. Been hoping it would arrive here though, esp with SE no longer involved.

Unfortunately it wasn't. Torment had -30% discount on GOG and is -50% now on Steam. D: OS was -50% on GOG and is -60% on Steam. Just to name few titles... I totally prefer GOG but it is pity that big sales discounts are different(

Fair do's. I already have those both on Steam so wasn't paying attention to their prices. None of the things I am interested in has dropped to a price that makes me want to jump on them. (Mostly been hoping GTA V would finally drop to 20€ or less)

i bought the Atari Vault :P
