I'm definitely on your side, as that's entirely bogus and my current employer just ran into a similar situation that has outed us $250k.
But...
"Return Policy:
RB Turbo LLC offers no returns on products purchased without prior consent. If a return is desired please email with your order number and we will determine if your order qualifies for a refund. If the order qualifies for a refund then pending on the product and timeline restocking fees up to 40% may apply."
They provided just a vague enough explanation of their return policy that you'd definitely think, 30 days - no harm, no foul. But what they actually mean is,
"hey guy, f**k you, you paid for it."
Keep it and resell it. Don't even give them the satisfaction of knowing that their scam works.

I'm in on the boycott of this company because that's the epitome of strong-arming your customers.
