> Which of the returns can be sold as new, which can be sold as-is, and which can be repaired / refurbished. What if a unit is returned once again? Did the customer return counterfeit? How to detect bad-faith actors (which may be the seller)? Who is to blame for damages? What if the item requires special handling (household chemicals, batteries, etc.)? And how to safely dispose / liquidate inventory while being compliant to all the regulations?

They just sell it in bulk and leave it to regular folk to buy pallets or containers and sell the shit on WhatNot.
