I DISAGREE!
I would buy almost ANYTHING from Amazon!
They back EVERYTHING 100%.
Several years ago I bought a flat screen TV from Amazon. Amazon promptly shipped through some company with "white glove delivery". The TV came from Prescott, Az, and was going to me on Cape Cod, Ma.
The total ship time was 12 days, and the TV sat in Boston for 6 of those days.
I complained to Amazon, but did not ask for any remedy.
Amazon gave me a $75 credit, and sent me an apology.
I did NOT ask for anything!
Am I loyal to Amazon? ABSOLUTELY!
HD and Lowes give me a 10% veterans discount on EVERYTHING!
Am I loyal to HD and Lowes?
You bet I am!
I will say though, that MANY items (same brand) can be purchased from other online sources, or E-Bay for less than Amazon prices. In many cases now, Amazon is also often required to charge sales tax, others do not, if they do not have an in state presence. Shipping is often free from others as well.
