I have never understood why people complain about the damage caused by the shipper and blame the people who sold it. As soon as it gets out of their possession they have little or no control over how it is handled, and there are only a few ways to ship an item
I have bought quite a few of Grizzly products, and have only had a couple things damaged in shipment, when I did I called and they sent the damaged parts to me no questions asked, and didn't even want the damaged part returned
Keep in mind that the manufacturer is the one who chose the shipper. If the shipper is not satisfactory and causes a lot of damage, the manufacturer should change shippers.
The manufacturer owns the responsibility of getting their undamaged product into your hands. Very often, they also step-up to the responsibility of getting your product to an operational state. If you bend or damage a component during assembly, many (most) manufacturers will make good on getting you a new part. They don't have to, but it is good for business.
Customers lie. A lot. I have no hard data, but it would not surprise me to learn that a very large percentage of warranty claims are actually "improper use or other customer-inflicted damage, but customer claims damage in shipment or manufacturer defect." Sometimes it is better for business not to question the customer, but write it off to customer goodwill. I am not saying that it happened in the OP's case, but that it is very common. It is amazing what excuses customers will make and what lies they will tell to avoid paying for something from their own money. Sadly these days, people will throw away their personal integrity for a couple bucks. I wonder whether they are self-aware enough to notice that loss.
I have found that strict honesty actually helps. I tell the manufacturer's representative that I broke it and I am willing to pay for the replacement part or whatever fixes the issue. Can they help me with this problem? More often than not, they send the part as a courtesy. Customer support people rarely get the honest, straight story. When they get a customer who admits that they messed up and damaged the item themselves, it is like a breath of fresh air. They want to recognize that honesty; it is as simple as that.
