csgo.cases is great and i've been using it since i started playing counter-strike. I always open the free cases because there's a good chance of getting something for free, and then there's the best part: the official cases, but much cheaper.
You also have the user cases, which you can create, and that's amazing.
You even have the shop where you can buy and send skins for your steam inventory. It's a safe website, easy to use and overall really great.
