Singer Justin Bieber sparked a holiday shopping frenzy last month (Dec10) after his debut nail polish range completely sold out across the U.S.
The Canadian pop star's glittery varnish collection was stocked on the shelves of 3,000 Wal-Mart stores in time for the Christmas holiday, and every bottle of the must-have item sold out.
Staff at the discount chain's headquarters also experienced difficulty as Bieber fans called their helpline to demand more of the product.
A Wal-Mart representative tells, "The call centre in Bentonville (Arkansas) was flooded and flooded with calls with people wanting to know where they could get the nail polish. We just couldn’t keep up."
