Rewards1 wants to hook you up with free League of Legends cards! If you're not familiar with Rewards1, they're the site who pays you to do stuff like watch videos, use their search engine, do surveys, and more. You can have them buy you just about anything you want, so if that sounds even remotely good to you please check them out, they've already paid me over $200 and that's a small amount compared to other users.
If that's not interesting to you, how about Gift Hulk? If you're at all familiar with SwagBucks then you should know what to do here. They've got League of Legends cards, Microsoft points, PlayStation Network cards, and lots more. Basically here's what I do:
*Install Gift Hulk plug-in to use search engine often, random searches may be awarded with coins (Gift Hulk's currency)
*Watch videos
*Do the daily poll
*Hit the Treasure Box
*Watch Gift Hulk TV, more videos for coins.
*Read the newsletter for codes
That's it. Doesn't get much easier than that and yet about every two weeks, I cash out for a $5 Amazon gift card. Hey, free is free. I'll take it all day. I've made $25 from this fairly new site, which gets better every day.
