Walmart's Prime competitor is ready for, er, primetime. Following some adjustments last month trimming the free shipping offer to two days from three for $49 per year, the giant retailer is ready to take its ShippingPass program nationwide. And to celebrate the rollout it will be offering a free 30-day trial or an extra month of service for existing members.

Walmart's move comes as Amazon is expected to launch a Prime Day sales event for the second year in a row, underscoring how serious the company is getting about online sales. The company has previously launched a handful of other programs , including online grocery pick up and a partnership with ride-hailing app Uber to deliver groceries.

The company says that more than 1 million items on its website are eligible for ShippingPass at the moment. Aside from free two-day shipping, customers also get no minimum order requirements, and returns are free – both online and in store.

Amazon's two-day service matches Amazon at half the price but to be fair, Amazon Prime includes other extras like streaming streaming music, video and more. The company also recently announced a $10.99 per month for those who do not wan't to commit to the full year.
