You can appoint 1 Bangboo as the Managerboo of the Sales Stall. A Managerboo will provide buffs to selling (not effective when the selling price bonus is lower than 1).
While a Managerboo is working, it will continuously drain Battery Charge. When its Battery Charge reaches 0, it will stop providing buffs to the player. A Bangboo that leaves the Sales Stall will begin to regain Battery Charge.
