Online marketplace Jet.com will stop rewarding shoppers for buying on other e-commerce sites.

Jet emailed shoppers Wednesday to inform them that it will pull the plug on its Jet Anywhere program on May 1. Jet Anywhere was an affiliate marketing-style offering wherein Jet linked to other retailers on its website and offered shoppers who clicked through and subsequently bought something a percentage of their purchase price in JetCash. That JetCash could then be redeemed for credit towards Jet.com purchases. Consumers will have until May 1, 2018, to spend their JetCash.

The Jet Anywhere offering rewarded shoppers for spending money at a number of Top 500 retailers, including the likes of QVC Group, No. 10 in the Internet Retailer 2016 Top 500 Guide, Lands’ End (No. 44), Nike Inc. (No. 47) and 1-800-Flowers.com Inc. (No. 57).

“Jet Anywhere launched when we were still in the early stages of building our product catalog; it was intended to help our shoppers save on items they couldn’t find on Jet,” the online marketplace wrote in announcing the move to shoppers. “Since then, though, our assortment has grown to over 20 million items and counting — and by shutting down Jet Anywhere, we can focus in on adding more great brands to the site and finding you innovative new ways to save.”

Wal-Mart Stores Inc. (No. 4) acquired Jet for $3.3 billion in August.
