Shoppers were stunned to see Mini Eggs priced at £15 a pack in one WHSmith store - three weeks after Easter.
Cadbury's Mini Eggs are one of the chocolate maker's most popular Easter products and many flock to stores to stock up on the treat whilst they are in.
However, this year shoppers have frequently shared their frustration at the cost of the much-loved Easter treat.
This year, the price of an 80g pack of Mini Eggs had risen by 25% compared to last year - and the high costs look like they haven't stopped.
Just this week, the WHSmith London Bridge station store priced a 1kg pack of Cadbury's Mini Eggs at £15 reports the Sun.
This huge price tag baffled customers as most major stores have discounted the product since Easter.
Currently, the upmarket supermarket chain Waitrose is selling the same 1kg bags at £2.50 across some of its branches.
Shoppers were further stunned to find out the £15 price tag was also misleading as the product actually scanned at £10 at the till.
Obviously, the price labelling of the Mini Egg chocolate was most likely an innocent mistake by staff at the stationary chain.
Mini Egg fans were quick to share their thoughts on the price tag with one shopper telling the Sun that they believed the pricing was "a joke".
They added: "A tenner is already steep enough to charge for them. I'm flabbergasted."
Another said: "It's almost a month since Easter. I wouldn't have paid that much for them even then."
A third said: "That price label nearly gave me a heart attack - although a 1kg bag of Mini Eggs might have done that anyway."
Like other food companies, the owner of the iconic British brand Cadbury's Mondelez International blamed the price rises seen on some of its products this year on rising costs for materials and energy.
The company did say it was trying to "absorb" the rising costs as much as it could.
Although, Mondelez International did note that retailers were free to set their own price for the product.
In a statement about the cost of Mini Eggs, Mondelez International said: "We are facing the same challenges that so many other food companies have already reported when it comes to significantly increased input costs – whether it’s food commodities, energy prices or packaging materials – and rising inflation.
"This means that our products are much more expensive to make.
"We understand that consumers are faced with rising costs too, which is why we look to absorb costs wherever we can, but, in this difficult environment, we’ve had to make the decision to increase the recommended retail price of Cadbury Mini Eggs 80g.
"Whilst we are making this change to the recommended retail price, retailers are free to set their own prices in their shops.”
A WHSmith spokesperson said: "Unfortunately, this was a mistake with our pricing labels, but we do love to give our customers great value and the good news is that these bags of Mini Eggs are still available at £10 while stocks last."
