It's starting to look a lot like the Great Recession redux for retailers.

More than twice as many stores have closed this year than at the same point last year. Bankruptcies are far outpacing last year's rate. Retailers slashed jobs at the sharpest pace in seven years this spring. And retailers collectively could report the biggest drop in first-quarter profits since 2009.

This time, the culprit's not the economy but shoppers whose habits have changed profoundly and permanently, as they shop online more and look for deals.

The results this week from department stores like Macy's, Kohl's and J.C. Penney are expected to illustrate the latest damage by the spending shift and the dominance of Amazon.
