Amazon right now has a bonus for purchases in their Android app store that also applies to some free apps.
The best part is you don’t even have to technically download the apps–just “buy” them.
Here’s the list of free apps, but not all of them work.
You get 200 coins for
downloading I meant buying, you don’t need to download. According to Amazon’s terms and conditions, a coin is the equivalent of a penny towards apps.
These are ones that appear to work:
The Doctor Panda Cooking Game (why do I see myself actually playing this one?)
I made it to the 100 Doors app and finally assumed the rest didn’t have any, but let me know if you see more!
h/t whichever friend mentioned this to me last night (sorry!)
Edit: Someone in the comments just posted a way to double your coins:
After getting 1,000 coins, you can turn 699 coins to 2,000 coins by buying another app: http://poorstudentblog.com/free-2000-amazon-coins-buy-grand-theft-auto-san-andreas/
