I agree with you and in my country we have similar law that protects the seller getting losses at this kind of mistake, when a consumer exploits it. But is needed to look at this specific case: since the GG were (are) in promo, with games at over 90% off (such as botanicula) how the consumer could with no doubt say that, for example, the Beth pack was some promo too?
PS.: I didn´t buy anything from GG.

My guess is: as long as Steam gets their profit cut (per key) the reseller can resell the keys as low as they want.

( PS: We are all not lawyers here, if some one is please step forward. And NO, playing Phoenix Wrigth - Ace Attorney does not make you a lawyer. ;D )

I would actually consider that deal, but it's €7.50 in Europe...
Steamprices shows $5 for the US, do you get different dollar prices in Japan?

They've had since August 2011 to take them off me. Strangely enough, I think I'll be OK (based on experience rather than random paranoia). Here, I think this is for you. :)

Also FO:NV at 4,99€ (3,50€ if the code works)

Wait wait wait, what the hell?

...

The game is more expensive in America than it is in Mexico?! ($4.99 in the US vs $3.49 in Mexico!)

Yep, the 30% code stacks here in the UK, making it £10.50.

Yes. It's been cheaper here than in the North forever, which is why I have helped some people to save a couple of bucks since the summer sale. For once Mexico has a price advantage.

Obviously Japan isn't getting the short stick for once. :) yes it's 3.74 here and $12.49 for the complete Edition. I can make a screen shot if you like.

Sry, didnt see, it was right above me.

OK.... See I made my analogy based on physical goods because software is, more or less, considered to have the same properties as physical goods and hence why piracy is classified as theft. Or at least that is my understanding of it. Perhaps M&M's was not a good example (teaches me for listening to my cravings I suppose).

However, your example of the tv is not a good analogy either. The right analogy would be you agree to some terms when entering the stire (includibg the ones you mention above) the sale has been completed and they (for whatever reason) accepted your payment. They then made an announcement saying that they made a mistake but you could keep the TV and people that ordered it but had not received it yet should expect delayed shipments for 2 months. Then, they cancelled the orders not yet delivered, in-delivery orders ancanaries into your house to take back the TV and left the mOney you paid or in some cases didn't even do that. Of course it cannot be a perfect analogy but I think this is as close as it gets.

Now in the real world when compared to physical goods, if such a price mistake were to happen, I am sure the law would pretty much say that if the transaction has occurred, the seller does not have the right to take back the item and force a refund in the customer via tracking him/her down to the address and so on.

Ps: I so wish there was a separate thread dedicated to this so the deals thread wouldn't be polluted by my posting :(

Link to those opinions please. I'd like to see the precedents and statutes they refer to. Also, keep in mind that laws and outcomes vary a lot from country to country.

The T&Cs are subject to the laws of each country. One cannot contract out of their statutory rights. Therefore, if the T&Cs are contrary to the scope of, say the Sale of Goods Act in England then they are void. And this is very, very commonly the case.

e.g. see UCTA
http://en.wikipedia.org/wiki/Unfair_Contract_Terms_Act_1977

e: IIRC a large part of the debate here is regarding whether the Sale of Goods Act applies to digital goods. I think that the last time I checked it didn't, but as far as I know, the debate is still open.

Isn't half the DLC missing for us? And for that matter I wonder if it's even compatible with "import" copies as the version they supply here on Steam is JPN/ENG only.
Don't be surprised if you lose those, even if you've added them to Steam already. They can, if they so wished, contact Valve and have those keys revoked.

Dead Island GOTY is 75% off at GG today.
