This is the reason an industry expert states as to why Sears has failed:
PETERSON: They're investing a lot in a rewards program called Shop Your Way. And this is also tied to their e-commerce site. And they're investing a lot less in stores, and as a result, stores have been languishing. Shoppers complain that when they walk in the stores, they can't even find a cashier to check them out, and that's a big problem.
