Of course, we all might be better off if we just stop shopping in stores altogether. As we reported Wednesday, consumers could save $640 annually by shopping with Internet access, taking advantage of exclusive online coupons and closeout sites like Overstock.com. For its part, Gap Inc., wants to be a bigger player in the online game: the company is planning to greatly expand its “ship from store,” model, which ships in-store stock to online customers. “Ship from store” will spread to Old Navy stores next year.
