If anything, I think that Sears focused too much on blaming the Internet.
I wish I could find it, but I remember reading an article, from 2015 IIRC, that dealt with retailers' misconceptions' about "showrooming" (customers entering a retail store to check out a product, then going home to buy it online for less) and "webrooming" (people going online to check out a product and then buying it in-store)
As it turns out, from the surveys conducted, about 20% of consumers engaged in showrooming, and 65% engaged in webrooming.
The top reasons were:
-The shopper did not want to buy a product without touching it first (trying on the coat to see if it fit, opening the oven door to see how heavy it was, etc)
-The shopper wanted to look for the best deal and learn about the product before making a decision to purchase it or even look at it in person
-The shopper did not want to wait or pay for shipping; they were also wary of "porch pirates", delays and breakage
-The shopper was unsure if they wanted the product at all and made a snap decision when they interacted with it.
The conclusion was that for a retailer to thrive, a robust physical and web presence is needed, so if they showroom, they buy it from your site and if they webroom, they buy it from your store. Most importantly, you need something that people want to buy.
Sears didn't have that. Before Sears Canada closed, I basically thought:
Clothes: Sears' aren't nice, and too expensive for what they are. For low-end stuff, Old Navy and Wal-Mart are cheaper, as are the TJX discounters. For mid-price stuff, mall brands have a wider selection, and for high-end stuff somewhere like Nordstrom or a specialty retailer/boutique would be better; and something like Nordstrom Rack has nice stuff for cheap. Specialty outdoor stuff you usually couldn't find there either.
Appliances: Home Depot, Rona and Lowe's have more selection and better prices, specialty appliance stores have stuff they don't
Tools: Canadian Tire and the three above have more and better stuff for less
Housewares: Walmart does it cheaper, Bed Bath and Beyond has more, Hudson's Bay has nicer stuff
Food and building supplies: They didn't have them
Electronics and Gadgets: Sears was a non-starter
Store experience is a big thing too, which is why Nordstrom offers valet parking, a shopping consultant, an espresso bar, free or inexpensive alterations, and the nicest bathrooms in the mall. Walmart is on the opposite end of the retail spectrum, yet offers its own range of services- a McDonald's, a discount haircut place, and a parcel locker service for stuff you buy online and not just for Walmart purchases. Both offer ship-to-store now as well.
At Sears? The stores were stodgy mazes, you were either hounded by staff or couldn't find any at all, and it was a running joke that you could never find a checkout, if you did nobody would be there and they were always out of stock on everything.
