John Lewis in Stratford is levying the charge for fans who want to gaze out at the panoramic view from their viewing gallery on the third floor.
But if you want to save your cash, you can since London Spy's spies headed down just before the Games and took these snaps.
It used to be free to take a look at the view - which is adjacent to the store's official London 2012 gift department - but the charges were brought in on Sunday after queues of freeloading gawpers made it impossible for most to get anywhere near it.
A John Lewis spokesman said: "This is something we've introduced from a need to manage the crowds.
"The net profit from our London 2012 shop in Stratford goes back to London 2012, and any proceeds taken from customers paying to visit the viewing gallery will be donated to local charities."
The shop is also giving fans the use of binoculars as part of the fee - but some were still outraged at having to cough up.
"I've come all the way down to London to see the Olympic Park. I'm surprised that I can't even get near it," Yorkshireman Paul Atack said.
"The park volunteers told me to go to John Lewis but I didn't expect to be paying for it."
