Surveillance video shows three men walked into his store, where he says they asked about trading in a gaming system for cash.
"Because it was a slow day, I didn't have any cash in the drawer," said Stanchek, who then told them to come back in a few hours.
Instead, the video shows two walking away, the third hesitating and then grabbing a jar full of money on the counter.
"It hurts. It really hurts," he said, because in that jar was more than $200 to donate to Children's Hospital of Philadelphia.
"They could have went and stole something from the store and that didn't bother me as much as this did."
In fact, he said there have been thefts at his store before, which is why he had this surveillance system installed in the first place.
Cheltenham Township police say they have this video and are investigating. Stanchek says he just hopes the suspects are caught.
The Stancheks put the surveillance video on Facebook hoping someone would recognize the suspects, but that's when the unexpected happened... people started donating.
So far, they've raised nearly $500, more than double what was stolen from them.
U-Save Car and Truck Rental of Glenside also donated $200 to replace the stolen funds.
"We appreciate it very much. We're just trying to make good on something that went bad," he said.
