Olson left La Crosse and relocated to Minneapolis to join prosperous dry goods seller N.B.

[5] The new company, called Ingram, Olson & Co., purchased inventory, along with a building located at 325 Nicollet Avenue, from the estate of Eugene Lehmaier in July 1885.

[6] By October 1886, Ingram, Olson & Co was the leading dry goods seller in Minneapolis,[4] with a newly remodeled store and expanded departments.

[15][16] While having the fire damage repaired, it was decided at this time to construct a new facade and expansion to the store in order to make it the largest retail establishment in Minneapolis.

[17] In an effort to further continue growth and expansion, Powers Mercantile leased Yerxa Corner in September 1906 so that they could expand their footprint in downtown Minneapolis.

[18] They constructed a new five-story building which expanded the existing structure from First Avenue to Nicollet at a cost of nearly $1,000,000,[18] which included the largest pane glass windows west of Chicago.

[19] In 1909 Powers Mercantile was one of two Minneapolis retail establishments, the other being Donaldson's, to shorten their hours to ease employee workloads.

[20] In a merger, Powers Mercantile became a part of a newly formed corporation in 1909, United Dry Goods of Delaware.

He became ill while visiting his son Fred, who had previously relocated to Pittsburgh, and was en route to a hospital in Rochester, Minnesota when he died.

The store continued to be prosperous, and Minneapolis was considered a healthy area of the country for the sale of dry goods.

[32] In August 1958 Powers disclosed they were further expanding their retail footprint in the Twin Cities by building a new stand alone 3 story store in the Highland Village area of St. Paul, Minnesota.

[36] During May 1971 Powers combined with Sears to purchase a 114-acre tract of land for a new mall to be built in Burnsville, Minnesota.

[39] They anticipated their sales volume would be greatly increased by doubling their retail space, concentrating on middle sized stores, and continuing to plan further expansions.

The two-story Northtown store reflected Powers' new image, with colors and lighting that were considered current, as well as boutique areas, and a luncheonette.

[45] At that time Powers ranked 7th among major retailers in the Minneapolis area, behind Dayton's, Target, Sears, Montgomery Ward, Donaldson's, and JCPenney.

[51] In 2004 when Dayton's successor Marshall Field's was acquired by May Department Stores, it also agreed to buy the former Donaldson/Powers locations operated by Mervyn's, and promptly shuttered them, selling the real-estate piecemeal.

Blaine, Minnesota's Northtown Mall location has seen many name changes, and as of 2020 was a Becker Furniture Outlet.

[57] The flagship store in downtown Minneapolis was demolished, and is currently the site of luxury apartments which opened in 2014.
