I was just at a Costco Business Center. They do fulfillment for the online grocery orders. They are shipping exclusively with FedEx. But when I recently ordered non-grocery items on Costco.com, it has come through UPS.
I had an idiot send a sample of some red liquid in a next day letter. Of course it leaked all over the floor of the truck. I had to use a customers hose to hose out the vehicle. What idiots.
What scares me is the amount of retail stores and websites that used to ship with us selling their products on Amazon. That’s what, for some reason, many people on this forum can’t seem to understand.
