I knew Sears was really done for when I went in there circa 2010 and they had a prominent computer with their "catalog", which was actually just searching Amazon. It's like these companies completely misunderstand what their value add is - I wasn't going to Sears because I was a "Sears customer" who only wanted to buy things from Sears, and they could hold onto me by letting me purchase Amazon items through them. Rather I went to Sears to see what Sears's selection was, and if they offered anything additional to what the HD/Lowes duopoly carried. They didn't really, and the rest is history.
Back in their day my Grandparents bought from Montgomery Wards or Sears Robeck (note they used the full name of both stores - odds are if you remember those stores at all is just by part of the name, or perhaps from a history book) They had a lot of stuff from those stores, and it was all good stuff, so they could confidently just buy it if the store sold it. In the final decades of Sears they often didn't have the best and so I had to think about quality (I don't remember Wards).
Amazon always mixed the best stuff with junk, but it was real - now who knows if it is real. Walmart used to be "made in the USA" (or made in Canada for stores in that country), but that policy is gone - they are still a step above dollar store, but only a small step: everyone knows you often get better quality elsewhere. Amazon mixed counterfeit with real not long after starting, while WalMart had "Made in the USA" for decades (made in Canada lasted a little longer).
There is a reason why some companies talk about the value of the brand. Coke needs to be very careful about losing trust (they almost lost it with "new coke" back in the 1980s - which my uncle says it was a way to introduce classic coke with HFCS instead of real sugar without losing the value of the brand - though he isn't in position to know what went on at Coke). My company often says we need to keep making high quality products to protect the value of our brand, we are well aware that we can rest on our brand reputation for a while, but bad quality has caught up to our competitors over decades and out market share shows is.
