Is Gamecarddelivery.com a scam?

Is Game Card Delivery safe and legit to use to get free gift cards, or it's either a scam or a site filled with viruses/malware?

This is my last resort since reward apps (like Rewarded Play, Freecash, Swagbucks, Google Opinion Rewards, Tapchamps, etc.) are useless! Go to this link if ou want to know what I'm talking about:

And here's the link to Game Card Delivery:

https://www.gamecarddelivery.com/

I visited the site recently, and there's one thing I overlooked. It's that I'm supposed to pay for them, and I thought someone running this site is supposed to do it and email me the code! Guess I wasn't paying attention...

How come no one else's commenting on this?
