Baum's solution to the financial woes of his family was to open a store, a bazaar, that offered the people of Aberdeen and travelers coming through, luxury items. The store opened in late 1888. Despite initial success, the store went broke the next year. The reason for this sudden failure was Baum's generosity in issuing credit to his shoppers, with terms that favored the shopper, not the store. Going broke and closing shop, the Baums once again struggled to make a living. Just a few buildings south of the store, Baum edited for a local newspaper, The Saturday Aberdeen Pioneer. However, after a year of this work, the Baums were were forced to move again. They settled in Chicago in 1891. It is in Chicago that The Wonderful Wizard of Oz would be published. It is believed that Baum's description of Kansas was based on his time in South Dakota.
The original store building does not exist today. Aberdeen's Storybook Land offers guides on L. Frank Baum's Aberdeen and the park has a section on Oz dedicated to Baum.
