Over the past year, hundreds of you have asked Whistleblower for help. While we can't investigate each tip, we want to share more of what you tell us. In 2009, we started publishing a few tips each week to stimulate online discussion and create ways for our readers to help each other. Unlike our news stories, we have not verified this information. If you have a tip, send it to whistleblower@startribune.com. A Minneapolis man didn't know what he was in for when he tried to buy a $299 chair that he saw in a major retailer's advertisement. He trekked to Burnsville to find the chair, but he was told he needed to go to the retailer's Edina location.

When he got there, he was told there would be an $85 delivery charge. He wasn't about to pay that high of a percentage of the chair's cost for delivery so he said he would pick it up himself. He was told to head to another location in Roseville, where he would have to pay a $25 pickup charge.

"They should advertise delivery and pickup charges and any add-on costs and requirements," he wrote to Whistleblower.

What are the strangest add-on costs you've encountered?
