NEW YORK ( TheStreet) -- GNC ( GNC) jumped 3.4% in its first day of trading on Friday after it priced its initial public offering in-line with expectations. The retailer, which sells wellness and nutrition products at 7,200 stores and online, sold 22.5 million shares at $16 each, for a deal valued at $360 million. In 2010, GNC earned $97 million on revenue of $1.82 billion. GNC competes directly with publicly traded Vitamin Shoppe ( VSI), which completed its IPO in October 2009. Already this year the retail sector has seen IPOs from designer Vera Bradley ( VRA) and men's apparel maker, Zuoan Fashion ( ZA). Toys 'R' Us is expected to issue its own public offering, which could be worth up to $800 million, this year. --Written by Jeanine Poggi in New York. >To contact the writer of this article, click here: Jeanine Poggi. >To follow the writer on Twitter, go to http://twitter.com/jpoggi. >To submit a news tip, send an email to: firstname.lastname@example.org.
