The company advertised an arbor nut for a Delta saw with a precise part number, which perfectly matches my Delta saw. However, the part doesn't fit -- the nut has the wrong thread. When I informed MadHornets of this, I expected a full refund because the part was clearly labeled wrong. But no - first they required me to send a video of the part's installation (it's a nut, for heaven's sake), which I did after some effort. After proving the part would not fit, their offer was a 10% discount and told me to resell the part. That's ridiculous - I don't need $1.78 back and then wrongly sell a $17.89 nut that doesn't match its OEM number.
