One big difference was that last year retailers kept promotions under tight control. Things were more panicky this year.
Retailers have planned their inventories very well again this year but there's no point in that if you get can't shoppers into your store. Expect substantial deals as we go along, especially in clothing and consumer electronics.
Lean inventories won't help retailers this year if they can't lure customers into their stores.
You see the guy out on the street selling coffee, donuts, fruit - his business is destroyed. There are a lot of small businesses that will close or that won't be able to pay their bills next year because of the strike.
