I recently purchased a refrigerator from Costco.com and had it delivered to my home last week. I have been a loyal Costco customer for decades and enjoy shopping at their stores frequently because of the outstanding "Customer Service". Truly a great company. That being said I must say I have had one of the "WORST" experiences ever when dealing with Innovel, the logistics company that is contracted to deliver products purchased over Costco.com.
My advise, when placing an order with Costco.com is to request any shipping company other than Innovel to manage the delivery. Innovel overbooks their drivers schedules causing late delivery times, they struggle to confirm appointments, but most of all some of their drivers have absolutely horrible customer service skills and should really be fired from the company.
