The e-tailer will open a discount shopping site for fashion, called MyHabit, on May 3.

Just like online auctioner eBay's Fashion Vault, which launched last year, MyHabit is modeled after successful sample sale sites such as Gilt or Vente Privee, offering discounted designer fashion for a limited period of time. But membership is free and instant, moving the destination away from the exclusive feel of the original 'members only' sales.

"MyHabit gives fashion customers an elegant and easy-to-use online destination for private sale shopping," Maria Renz, the site's president, said in a statement. "Couple that with a curated selection of the best brands, free shipping and free returns, and new features like 360-degree video footage, and MyHabit sets a new standard in service, convenience and product presentation."

Doo.Ri, Elizabeth and James, Halston and Vera Wang will be among the first brands made available on the new site, spanning men's, women's, and children's collections with discounts of up to 60 percent.
