Quote: Many manufacturers include the "do not return. call us" note. They want to avoid unnecessary returns from customers who might have an easily solvable problem.
Yep, that or simple buyer's remorse. Resellers should not have to eat those returns.
The Amazon policy undermines the return policy which both manufacturers and sellers have been trying to educate the public about for years (at least in my industry). I've never seen generally less-informed shoppers than those on Amazon - I get their email every day...
(But Amazon descriptions are full of errors, so it is also a contributing factor).
