Wal-Mart to test unlimited shipping

NEW YORK — Wal-Mart will test a new unlimited shipping service for online shoppers this summer that will be priced below Amazon’s widely popular $99 per year Prime service.

Wal-Mart, the world’s largest retailer, said the shipping subscription service will cost customers $50 a year. Products will arrive in three days or less. T

The unlimited shipping program marks a substantial commitment and underscores how serious the retailer is about accelerating the growth of its online business, which has seen a slowdown.
