• a transceiver;
• a control circuit coupled with the transceiver;
• and
• a memory coupled to the control circuit and storing computer instructions that when executed by the control circuit cause the control circuit to:
• wirelessly communicate an instruction to the first motorized transport unit and direct the first motorized transport unit to transport the first product pick unit to a determined first location within the shopping facility proximate to where a first product having been ordered is located;
• and
• wirelessly communicate an instruction to the first product pick unit cooperated with the first motorized transport unit and direct the first product pick unit to retrieve the first product;
• wherein the central computer system in wirelessly communicating the instruction to the first product pick unit to retrieve the first product is configured to communicate an instruction to the first product pick unit to adjust a vertical location of a catch pouch relative to a vertical location of the first product prior to the first product pick unit retrieving the first product.
