Getting the DLC for Prey from a grey-market key site.

Caveat emptor.

I mean, you can buy two keys and worst case you're losing a dollar. The websites themselves are pretty legit, I've bought from Gamivo, Kinguin, CDKeys, and G2A before, but you should read everything before clicking to avoid hidden fees like the "protection" that they offer. On something this cheap, you're better off just buying another key if it happens to not work the first time. Other than that just look at the key sellers/providers and pick the ones with the price to feedback ratio you're comfortable with. If the seller sold 200K keys and has a 99% positive feedback, chances are keys they sell will activate with no problems. Assuming of course that the sellers are real and not made up by the storefront.

There is always risk, even when buying direct. The best you can do is understand and limit it.

I'd describe these sites as "honest thieves" from a customer point of view. In the rare case a key fails to activate you'll get your money back if you provide proof with screenshots of your activation attempt and your license history.

Sure these sites accommodate merchants selling keys fraudulently acquired with stolen credit card credentials and money laundering takes place but why should you care if a small studio/publisher loses a few hundred thousand bucks through charge backs and goes potentially bankrupt?(sarcasm)

In your case though Arkane will be able to eat up the loss especially when no key is available on more trustworthy sites.

IIRC, CDkeys is "not as grey market" as the others listed, because their system is centralized (meaning they are the only sellers, no 3rd party involved) and the keys are bought from regions where they are cheaper. I don't really remember where I read this, so take it with a grain of salt.

CDkeys and allkeyshop both have twitch accounts with constant streams. While AKS is mostly advertisement, I connected to CDkeys' a couple of times and it was a person (same guy both times) playing games. I imagine he probably is an owner of the website or smth.

Good luck in getting the DLC!

OMG
Just go ahead, I mostly agree with NucularS, they are spot on. But I still wouldn´t buy 2 keys. in case it really doesn´t work, I´d go through support and withdrew my payment asap.
Ah -keys.
So, if you´re used to buying on Steam directly ofc you never see the thing, but basically everything available on Steam is identified via a, I believe 15 digits, code. Back in the day when you still bought hardcopies, because download-times were abysmal, that code would be printed on one of the CDs or the inner sleeve of the package.
This code/key has to be redeemed on Steam (bottom left corner in the client), to identify the product and bind it to your account.
Nowadays when you purchase anything outside Steam, be it with official retailers or on the flea market these reseller platforms mostly are, all you get is such a key you then have to enter with Steam to activate your product.

Looking at your case specifically, if you want to be on the safer side, I´d go with one of the offers of either CDKeys or K4G, because they are not marketplaces, but normal albeit seemingly inofficial retailers, who sell their stuff on their own behalf.
You can easily spot the difference, because they don´t list a variety of offers with different prices for the same thing.
I´d also recommend having a look at gg . deals - they do pretty much the same as allkeyshop with a little extra.
Also I realized that CJS one isn´t listed with gg . deals - maybe stay away from them, at least that´s what I would do!

: ) cheers

edit: lol, there´s been a little traffic, while I wrote the above ..
The buying games with stolen creditcard data to resell them later scheme - I believe this mostly to be an urban myth, I can´t imagine this being in the slightest profitable for organizations capable of acquiring hacked credit card data in bulk. Also no idea where those charge backs for the devs should come from ?

Something else about what you´re after in peticular, because it is a rather special case. I´m certain in purchasing that Cosmonaut pack you´re doing Bethesda a favour !
Being a pre order bonus, it seems Bethesda didn´t know how to get rid of the leftover keys they must have had. They themselves had to put it on the so called grey market, because they could hardly put it with their officially licensed retailers after they had promised their initial customers that it would be preorder only !

Try the dark web

Also no idea where those charge backs for the devs should come from ?

once the legitimate owner of the credit card realizes the card was used in an unauthorized transaction he'll report the fraud and the credit card company will issue a charge back from the seller e.g. the publisher/developer. Thus they don't get paid for the keys and have to pay the charge back fee.

Edit: G2A is always in the spotlight but that doesn't imply other sites are less likely to facilitate fraud and money laundering.

Oh thanks i didn't know abou this DLC, i got it now.

im not fond of the grey market but Cdkeys has been good to me over the years

I don't touch sites like that. Key could work sure.. But could also get revoked at any time.

Thought you are about buying Mooncrasher dlc. As not story dlc it wouldn't worth to me these 40 cents, not even having to put dirt on grey market.

I personally would make sure it's a gray market, not a gray marketplace. So basically all the keys coming from the site itself, not from random users. The sites with the random users will have occasional scammers, almost guaranteed terrible support, hidden fees, payment fees, all that absolute nonsense. The cheapest one I saw on that list was CDKeys. They get their own stock, they sell their stock.

As cheap as it is, don't think it's worth getting. I got the cosmonaut pack with the game and honestly don't even remember using it in-game.

Some of these sites have an extra safety payment (it either comes by default or you can add it) to assure your key is valid. If it turns out it's invalid, you can always contact their support to solve your issue. I once bought a cheap key from one of those sites and it was supossed to come with 2 games but I only received one; I contacted support and they gave me a refund.

If the rating of a seller is more than 98% I'd say it's a good bet. At least I personally wasn't scammed there once, and I used Gamivo quite a lot. There can't be 100% guarantee though. But then again, for more than 95% discount it's worth it (I think). But it's up to you to decide whatever you want to use this kind of sites or not.

Hey,

Reselling keys and links to reseller stores. Do not use our site to resell keys, and do not post offers from stores which allow third parties to resell their keys or gifts. For example, do not ask others if they are interested in buying your leftover keys from a recent bundle purchase, or link to keys for sale on sites such as Kinguin, G2A, or Eneba.

I will close this thread for now. You can edit it and ask in general about legitimacy of keys sold via grey market sites. But it's not allowed to link to them in any way.
