4 year old Sawyer racked up huge bills on his momma's iPad.  With a free download.

"The Smurfs' Village," a game for the iPhone and other Apple gadgets, was released a month ago and quickly became the highest-grossing application in the iTunes store. Yet it's free to download.

So where does the money come from? Kelly Rummelhart of Gridley, Calif., has part of the answer. Her 4-year-old son was using her iPad to play the game and racked up $66.88 in charges on her credit card without knowing what he was doing.

Rummelhart had no idea that it was possible to buy things — buy them with real money — inside the game. In this case, her son bought one bushel and 11 buckets of "Smurfberries," tokens that speed up gameplay.

"Really, my biggest concern was them scratching the screen. Never in my wildest dreams did I think they would be charging things on it," the 36-year-old mother said.

She counts herself lucky that her son didn't start tapping on another purchase button, like the "wheelbarrow" of Smurfberries for $59.99.

Rummelhart joins a number of parents who have been horrified by purchases of Smurfberries and other virtual items in top App Store games. The 17 highest-rated comments on "The Smurfs' Village" in the App Store all complain about the high cost of the Smurfberries, and two commenters call it a "scam."
