I think the issue with Sears is they had a ton of large brick-mortar-stores (often the "anchors" at malls, which is another nearly dead industry with the last indoor mall built in the US in 2006). Remember the fear of Wal-Mart killing main street in the late 90s into the 2000s? Wal-Mart came in and killed the competition, which included Sears. Then Amazaon annihilated Sears further and took a huge dent in Wal-Mart. Sears had no choice but to implode. I imagine major horse and carriage companies suffered a similar fate with the invention of the automobile.
I’ve posted this before but I was fooled by a StubHub setup that looked like it was the venue itself - and not accidentally. So when I bought a ticket I was shocked to get an email from StubHub.
When I double checked and found the venue I had overpaid by 100% and StubHub refused to refund me.
