John Lewis is charging £2 for visitors to look out across the Olympic Park from a viewing window in its Westfield Stratford store.
A spokesperson for the retailer explained that two separate queues have been set up- one allows customers who want to shop in the London 2012 outlet to enter for free and the other is for those who want to pay to get a glimpse of the park.
In a statement, John Lewis said: "We have introduced a small charge to enter the viewing gallery at our Stratford shop - £2 for adults, under 16 years go free - as operationally we felt the need to separate those customers who wish to visit the London 2012 shop and those who wish to experience the view.
"This is something we've introduced from a need to manage the crowds."
The retailer added that all the proceeds from spectators visiting the viewing gallery at the store will go to local charities.
The good causes being supported by the move are East Thames Potential, Cardboard Citizens and The Panathlon Challenge.
The news comes following criticism from would-be spectators about the inability to purchase tickets for Olympic events.
More recently, those that could get access to the park complained about a lack of shelter from sun and rain .
Some spectators tweeted photos of people huddled under a bridge to keep out of heavy downpours.
The complaints came as visitors realised only venues and a 1,500 seat fast food restaurant offer cover.
