Myer has seen sales dive 3.3% to $653 million in the three months to March 31.
The department store chain’s total year to date sales fell 1.3% to $2.44 billion.
The news saw its share price dip to 98c on Thursday, following a sharper 17% free fall in the past month.
The first tumble was sparked by comments from Credit Suisse analyst Grant Saligari, who warned the arrival of Amazon andTK Maxx would significantly hurt Myer.
Poor third quarter results were attributed to challenging trading conditions, severe weather conditions and falling sales at Sass & Bide.
Despite its woes, Myer confirmed a strong 36% growth in online sales in the year to date.
Myer CEO and Richard Umbers confirmed the department store is still on track to hit full-year guidance forecast.
