do you get your money back if you send it back? (it is the case where I live, but I think it is not mandatory everywhere)
if enough people send it back, the costs for amazon might get high enough to take care of the problem. although I am guilty of not sending back defective 5€ to 10€ items as the hassle was not worth the time at that moment
Same here, time is a very scarce resource for me, so I confess that if the item is cheap I don't bother to send it back because I consider the time it takes to be more valuable than the refund.
