I've sold a ton of pairs without issue. Recently sold some HyperAdapts, they got denied due to 'being tried on.' I told them that Nike+ had me try them on to test the sensors before leaving the store, which is true. Apparently there was a small mark on the bottom of one of the shoes that I didn't even notice. Anyway, so they shipped them back... I had sent them well packed with bubble wrap/peanuts in a 200lb test box. They returned them in a 44lb test box with 'paper' as packaging material. I opened up the package, found scratches all over the bottom of the inner blue box and discovered when opening the box that the charging pucks weren't in place and had been thrashing around during shipping. As a result, there is now 'permanent' cosmetic damage to the charging pucks. I took the tracking number and put it into USPS to file a claim and it said that there was no insurance purchased for the package... a $2k+ pair of shoes, weighing in at 12lbs, in a 44lb 'max weight' box. I contacted GOAT and explained what happened and told them that I need to file a claim as they literally knocked hundreds off the value of my shoes. They're currently giving me the run around, though I'm considering taking legal action because this is really getting under my skin. Thankfully I took photos of the box/accessories in pristine condition before shipping them out.
