In the wake of a series of online scams that included tricking Walmart into selling the PlayStation 4 for $90, the retailer changed their online price match policy.

Earlier this week, some customers began using fake listings on Amazon.com to purchase a $400 PlayStation 4 for less than $100 with the help of Walmart's new price-matching policy.

Yesterday, Walmart announced they were changing their policy to protect the company from fraud.

"We launched online price matching because it's the right thing for our customers," according to a statement from the company. "It's making a meaningful difference for people who want to feel confident they're getting the best price, and we're committed to matching online prices going forward.



"At the same time, we can't tolerate fraud or attempts to trick our cashiers. This kind of activity is unfair to the millions of customers who count on us every day for honest value. With this in mind, we've updated our policy to clarify that we will match prices from Walmart.com and 30 major online retailers, but we won't honor prices from marketplace vendors, third-party sellers, auction sites or sites requiring memberships."

Under the new policies, the item being price-matched needs to be currently in stock, the retailer reserves the right to verify the item and Walmart will no longer honor prices from marketplace, third-party sellers, auctions or misprints. The store also has a list of which online retailers, including Amazon.com, that they will price match.

Walmart officials say they're also continuing to tweak their policy to make sure it's working for both themselves and their customers.

"We will continue to listen to feedback from our customers and our cashiers to make sure our online price match policy is working," according to the statement. "Customers with questions can read the updated policy by searching ‘online price match' at Walmart.com."
