All they had to do was have the foresight to move that model onto the internet. They had the supply chain, warehousing, etc. They may have even been able to have done their own logistics, since every city had a Sears. Kinda how Walmart does deliveries now.
And as you mentioned...they got crushed by a bookseller :(.
Amazon was the right size to grow with the market. Amazon didn't even start selling clothing until 2002.
Service Merchandise hit some weird bad luck in early franchising (and franchising may have been the wrong choice/it's own bad luck) and accidentally got somewhat region-locked into the US South East, but the business model was from today's perspective ahead of its time, directly addressed that "mall shopping need" while still keeping what made catalogs and drop shipping useful (and relatively efficient just-in-time logistics).
Sears seems like it could have transitioned if it didn't have its head up its ass. The death of film means Kodak would have to constrict and double down on printing, and simultaneously expand their general chemistry efforts into new markets (which I believe they did but too little too late).
How a company that was focused on their legacy customer relationship system and logistics operations lost out to a company that was focused on building the future of customer relationships and logistics is a lot less difficult to understand.
I remember it differently. Also, actual history is different too.
> Bezos finally decided that his new business would sell books online, because of the large worldwide demand for literature, the low unit price for books, and the huge number of titles available in print.

Selling books was never the ambition, it was only the path.
Sears, after dominating mail-order for a century, marketed Prodigy, a successful early dial-up network. But they were by that point heavily invested in malls, and were beat out as the 21st century's Sear's, Roebuck and Co. by a bookseller.
