lululemon athletica, a high-end retail chain dedicated to yoga and fitness apparel, recently experienced several years of record growth.

Founded and headquartered in Vancouver, British Columbia, lululemon manufactures and sells technical athletic wear aimed primarily at active men and women who are willing to pay premium prices for workout gear. These high prices have allowed the retailer to maintain a gross margin annually above 50% since 2003.

Although the initial goal was to have only one store, consumer demand has resulted in multiple locations.

Most stores are located in major cities in Canada, the United States, Australia, New Zealand, and the United Kingdom, as well as in Singapore. lululemon's huge sales growth can be largely attributed to the company's extensive store expansion.

To reach even more customers, lululemon launched a successful e-commerce operation on its company website in 2009. After posting its best-ever first quarter, lululemon said that its priorities were to grow existing stores and to invest more in its thriving online division. On its company website, Lululemon reported a 30% increase in traffic to its e-commerce site in 2018 with its e-commerce efforts netting US $476.9 million in sales, compared to US $421.1 million the year before.

The company offers regular-priced in-store products online. It also offers discounted men's and women's athletic wear under its "we made too much" clearance link.

The following items were recently discounted on the lululemon website:

Women's Wunder Under Pant: $69.00 CAD (was $88.00)

Women's Get Started Jacket: $49 CAD (was $118.00)

Men's Cardio SS Tech Top: $24.00 CAD (was $58.00)
