I worked in retail for a while, and it was staggering to uncover that the majority of people with the control over inventory thought the same way.

• It takes 21 days for an ordered item to arrive at the store
• A manager orders 5
• 21 days later, 5 come in
• 2 days later, all 5 are sold
• A month goes by and the person sighs, frustrated that they have to order more while simultaneously not understanding why sales are down.

Have you ever considered ordering 10 or 20 to see if they sell out in 4 to 8 days or less? Maybe then order 40 or 60?
