EAGLE-eyed bargain hunters have rushed to social media sites to lampoon Myer for a grammar clanger in seven-storey-high banners erected across Australia.

The department store recently unveiled a new campaign in stores across the state for Boxing Day with the slogan, “Early bird get's the right size”.

However, the apostrophe wasn’t necessary and the retailer has copped criticism, thanks to a mini-meltdown from punctuation enthusiasts across the country.

Twitter users have exposed as many spelling and grammatical gaffes by the company as they could find.

One user wrote: “Who needs proof reading (sic)” while another was “apoplectic” over the apostrophe.

The seven-storey banner inside the atrium plaza of the flagship Myer store in Bourke St, Melbourne was the target of many shoppers' ire.

The Herald Sun today featured another sighting in our In Black & White column, with reader Raffaele commenting: "Why on earth would anyone think that the word ‘gets’ would need an apostrophe?”.

A Myer spokesman admitted the advertising error had been rolled out in-store, across all stores around Australia.

“Myer are aware of and have corrected the punctuation error in some of the Stocktake Sale signage,” he said.

“We offered our sincerest apologies for this error to customers who took the time to raise this with us”.

Staff operating the company’s Twitter account have begun to respond to its ridicule and went as far as jesting about its support for the Stocktake Sale.

“Thanks for all your feedback on our printing error - we’re getting this fixed at the moment!” said its first tweet on the subject at about 3pm.

“And we’re glad you’re all so passionate about our great new Stocktake Sale creative!”

Following the raft of criticism the terms “apostrophe” and “@myer_mystore” have trended on Twitter.

Myer admitted to another spelling error on a second sign featuring the word “Satruday” instead of Saturday.

It is not clear when, or if, signs will be changed, but it is understood the banner advertisement in the Melbourne store can't be changed until after-hours.
