My phone has this super quiet noise that is so calming and doesn't wake up the wife when it goes off. It is such a soothing way to wake up. That $15 alarm clock? That's a klaxon alarm letting you know that Armageddon has started.
My alarm clock, purchased as an undergraduate in the 90s, has never had any bugs in its alarm or clock functionalities, and comes with (red 7-segment LED) digit display that's larger than my phone. I do think it was more than $15, even back then, but it's lasted a long time.
After I realized I could buy, brand new, many of the items I was looking for for a couple dollars more, and sometimes a couple dollars less (they left the original price tag), I mostly stopped going. I went back in for the first time in a couple years and it was just ridiculous. I have to assume their real purpose is some sort of tax benefit at this point, because none of it made sense, besides the clothes.
I’ve seen cheaply made kids toys for exactly what they cost brand new. Goodwill has been going downhill. I’ve seen on numerous occasions employees breaking fragile items on drop off, no regard. I might as well trash them that give them to someone else to do the same.
That depends on whether or not you'd consider "setting an example for your kids" in this particular way as necessary or not. If you think that's valuable, then this isn't an unnecessary duplicate. If not, then sure.
