A trend is starting, or has started, where games are being offered free, with the ability to 'buy' additional items while in game. Now for instance, and this is partially my fault, my nephew who is 6 downloaded a free game yesterday, and the next thing I knew I'm seeing all these "Thank You for your order" emails charged to my account. It's a very deceiving practice for people who let their kids play with their older phones or new phone. As some games, you can earn point to BUY upgrades, the ones I am referring to have a similar BUY option to upgrade but charges you. Now I know the difference, but when I child is playing a free game and they see BUY, they don't know they are being charged real money for the purchase. Just a heads up.. now I'm out $6 for some Bunny shooting game, with no refunds available..
