A Consumerist reader was scammed into giving a donation to Livestrong that he didn't consent to, as he found out when he got home and discovered an unauthorized donation on his receipt.
Here's the quick version: employee asks for a Livestrong donation, guy declines, employee charges him for a donation anyway. The customer has been calling and asking for a refund, but all Radio Shack personnel keep telling him to waste gas driving back to the store to get his dollar back.
Yes, it may just be a dollar, but it's called a donation for a reason. Make sure to check your receipts when you exit the Shack, it smells like RS employees are getting some sort of kickback for getting Livestrong donations. [Consumerist]
