NEW YORK – This holiday season, Burger King won't be the only place where you can have it your way.

It used to be enough for stores to promise discounts of up to 70 percent off to lure shoppers during the busy holiday shopping season. But the ease of ordering online and the sluggish economy has created more demanding U.S. consumers who aren't impressed by discounts alone. They want their shopping just like their fast food: not only cheap, but convenient too.

That means they're no longer afraid to walk away from the cashmere sweater with the perfect fit if the store is crowded. They're also unwilling to buy those suede pumps that are just the right shade of blue if they have to pay to get them shipped. And they cringe at the prospect of carrying around a bunch of paper coupons; they'd rather be able to pull them up electronically on their smartphones.
