Late last year, for example, discount chain Walmart created a buzz when it started selling a leather bag online that resembled Hermes’ coveted Birkin bag. The $78 item — sold by Kamugo, which doesn’t appear to have its own website — was a fraction of the price of the original, which goes from $9,000 to hundreds of thousands of dollars on resale and auction sites. Influencers labeled the leather bag a “wirkin.” Other suppliers including BESTSPR, YMTQ and Judy were listed on Walmart’s site selling similar totes.
