Walmart is launching the membership program Walmart+, its much anticipated response to Amazon Prime.

Membership will be available to all U.S. customers on Sept. 15. It will cost $98 a year or $12.95 a month and includes a 15-day free trial period. Members will receive unlimited free delivery from stores, fuel discounts and cashierless checkouts. Delivered goods will be sold at in-store prices and clients can choose from more than 160,000 items.

Walmart already offers a subscription-based home delivery service called Delivery Unlimited, whose subscribers will automatically become Walmart+ members.

Walmart also confirmed that it had agreed to sell Shoes.com to CriticalPoint Capital, the private-equity firm and the online lingerie brand Bare Necessities to the Israeli company, Delta Galil Industries.

It stressed that the two online platforms have enabled it to improve customer experience, add content and substantially increase its assortment in footwear and lingerie. Both businesses now sell most of their products on Walmart.com, the company added.
