Just make sure any site you are accessing to get them is legit.

Yes. Bear in mind though, many websites of that nature are scams and will not actually give you a code. I recommend avoiding them altogether.

By the way, game codes can be redeemed here: https://store.steampowered.com/account/registerkey (different from wallet codes)

We didn't say they were or weren't...just making you aware that you need to do your home work when dealing with any site where you can get things like this.
All the other Admin did was recommend that you avoid them altogether. What you do at the end of the day is still completely your choice.

I'm not commenting on any one particular site, but you should know there is a huge industry surrounding fake reviews and review manipulation, far beyond just Steam.

If it's a website you already know and trust, or have credible sources to confirm its legitimacy (e.g. someone you know who used it, not someone adding you on Steam or a bunch of positive reviews on their own site) then by all means enjoy it. But this type of website is a very common scam, so if you don't want your email getting spammed to the point of unusability with nothing to show for it, you should exercise extreme caution. If it were me, I would assume any website even remotely matching your description was a scam until firmly proven otherwise.

Truth be told, I actually fell for a scam which sounds just like what you described around... was it 10 years ago now? The site promised gift cards for something, I forget what, might've been Amazon gift cards or iPhones or something. At the time, I figured they weren't asking money, so I was probably safe. What happened was they kept increasing the bar for what I needed to "redeem" my rewards with. First I just had to give an email address and get a free iPhone or gift card or whatever it was. Then I had to refer at least 5 friends and wait for them complete their sign-up. Then I had to select "activities" to earn points with, including marketing surveys, visiting their partners' stores, registering on websites, sitting through ads and infomercials, etc. Then the number of points required increased and it got to be like a week-long full-time grind. Then after all that, I had to spend a minimum of $100 on at least 10 of their sponsors' websites before I could redeem anything. Never at any point did they give me anything for all this, not even a $5 gift card. It was all a foot in the door style scam, and they had me from the very beginning - my email was still practically unusable with all the spam even 5 years later when it got shut down. If you want to ignore my warning, then go ahead and learn the hard way. It's your life experience, not mine.

I've hidden that URL, definitely don't want "free steam code" links floating around. If it sounds too good to be true, it probably is.
