The Shop ’n Save Pharmacy in Union will soon become a Schnucks pharmacy.

The St. Louis-based grocer Schnuck Markets Inc. announced Monday it has entered into an agreement to purchase 19 Shop ’n Save stores. Included on the list is the standalone Union pharmacy located at 500 Highway 50 West.

The sale is slated to occur in October. According to Schnucks, the company will have a staggered closing process where stores will be closed for multiple days and reopen as Schnucks stores.

The stores are being purchased from Supervalu, parent company of Shop ’n Save. Of the 19 stores purchased, 14 are in Missouri.

“Schnucks is proud to be growing in our hometown of St. Louis, excited about the opportunity to serve new customers, and looking forward to welcoming the employees at these 19 stores to Schnucks,” said Todd Schnuck, chairman and CEO of Schnuck Markets in a press release. “We want longtime customers of each store to know that we are eager to earn your business, and we’ll be working closely with Supervalu and Shop ’n Save to ensure a smooth and successful transition.”

Part of the sale includes purchasing the pharmacies attached to the store and the standalone Union location. It said it plans to operate all under the Schnucks banner.

In addition to the pharmacies, Schnucks also is acquiring the prescription files for 10 additional Shop ’n Save in-store pharmacy locations and transferring those prescriptions to nearby Schnucks stores.

Customers of the closing Shop ’n Save pharmacies will be mailed detailed information on the transfer of their pharmacy files within the next several days, according to Schnucks. Information will also be available for customers at each pharmacy.

According to a release, Schnucks plans to retain the employees already working for Shop ’n Save. The store said it will complete background checks and “all bargaining unit Shop ’n Save employees will be offered a position at the same wage rate, working a comparable number of hours and doing comparable work.”

All Shop ’n Save store directors, assistant store directors, pharmacy managers, and pharmacists will also be interviewed by Schnucks over the next week, the grocer said.

Union Store

The Union Shop ’n Save Pharmacy was previously Rinderer’s Drug Store. Rinderer’s was purchased by Shop ’n Save in October 2010. A month later, the pharmacy was rebranded as a Shop ’n Save pharmacy.

Rinderer’s was owned by the Carlisle family, who owned and operated the store for nearly half a century. All of the six Carlisle stores were purchased by Shop ‘n Save.

Three of the stores were closed, but the closures did not affect the Union location.

Prior to the sale to Shop ’n Save, Rinderer’s was remodeled and celebrated a 25th anniversary. During the remodeling project, the store opened a drive-through window where people could pick up medicine without leaving their vehicle.
