Costco revenue exceeds $170B annually.  They offer items from health and beauty to hardware and household.  Their sales are driven by treasure hunt buying; focusing on purchasing items in mass quantity and distributing to hundreds of stores to be sold as quickly as possible.  Items found typically have no competitive product, causing sales to be successful and resulting in a sellout.  Members know to buy NOW or the item is likely to be sold out on the next visit.  Sales are driven on perceived and experienced demand.  The next item, likely new but similar, is then brought in with the same result.  This phenomenon is what drives vendors to source seasoned Costco brokers.  VendorCo can help-visit www.vendorco.com or email [email protected].
