Andres4NY, I generally try to avoid shopping on #amazon (for various reasons), but my rule is that if something is only available on amazon or is much cheaper, I will shop there.
I bought something recently. They added me as a Prime member (I didn't click anything to become a prime member, but apparently I didn't uncheck something so they gave me a "free" month; which I don't actually need or want) and have been spamming me about Prime crap. And now my item arrived, and part of it is missing.
