Walmart is known for its deals: Customers come back again and again for low prices on a wide array of products. However, regulars have pushed back against the retailer because it can't always accommodate all customers. 

A new change is soon coming for veterans and their families if they fill their prescriptions at Walmart. The news source says Express Scripts, a pharmacy services company that serves more than 9 million active service members and their families, has withdrawn its agreement with Walmart to serve as a pharmacy provider for the TRICARE network.

Both Walmart and Sam's club will end their partnership with TRICARE pharmacy network effective Dec. 15. After that date, TRICARE prescriptions filled at Walmart will then be considered out-of-network, and beneficiaries will be required to pay the entire bill fully and only file claims with Tricare for partial reimbursement.

In an interview with KNWA, Walmart's vice president of payer relations, Luke Klein, said the retailer was surprised by Express Scripts' decision to end its contract. 

Earlier in September, the retailer signed another multi-year agreement to serve as a pharmacy provider for the TRICARE Network.

But Walmart is not backing down. KNWA reports that Klein hopes to resolve with Express Scripts that allows the retailer to "continue being a Tricare pharmacy provider."

Klein said this decision would limit the options available to military members, veterans and their families. Walmart will offer everyday low prices on generic drugs to all customers, regardless of insurance.

Walmart, according to KNWA, is committed to supporting military-related individuals through other initiatives, including hiring 250,000 veterans, creating a platform that will aid those transitioning from military to civilian life, and granting millions of dollars to organizations that support veterans and military spouses.

Walmart stated that it has supported providing pharmacy services to military communities for many years in a separate statement.

A spokesperson for Express Scripts said that Walmart will no longer offer military health discounts because of its unwillingness to deliver "more highly competitive discounts." Their three-year contract expires this month. CVS Pharmacy, however, is returning to the TRICARE network after a five-year absence, according to Luddy.

Luddy told the news outlet, "This will make Tricare's pharmacy benefit more competitive and will widen the choice of quality, convenient pharmacies nationwide."
