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.
