Query: End of the line

My last purchase at amazon.com. I bought two alarms. One worked, one did not. Alarm horn did not sound. Had a previous problem buying a blood pressure machine, grotesquely misdescribed on the website. I have heard that Amazon has a no-return policy. Really does not matter. My time is too valuable to pack, address and go to the post office. Bye Amazon. Bye First Alert.
