Jim/Bladez showed me this website. You can find some really nice deals on it. Right now a lifetime premium license for Malewarebytes is going for $0.62. Just download the free trial, purchase one of the keys from here and use it to activate the product. Purchasing from this site is a bit tricky at first though. There will be multiple people selling the product, make sure you buy from the people with a lot of ratings at 100% and uncheck G2A shield before you purchase anything from this site otherwise they will pin you into paying $1.11 for that. They also charge you $0.41 for all purchases. So Malewarebytes will actually be $1.03, but that's still a steal for a lifetime premium membership. There are also a lot of games you can buy on here which you can get steam keys for or uplay codes. Just thought I would share it. The Malewarebytes deal is only going on for the next 11 hours I think, but if you see this in time I highly recommend it. Also you can purchase stuff without making an account which is nice.
https://www.g2a.com/Note: After you make the purchase, don't get nervous when it says "Average Wait time: 5 minutes." It takes time to process the CD Key, but after the time is up it will give you a button that says "Redeem CD Key" or something along those lines. Click on it and then click the checkbox, it will then give you the key you bought.
