Mark McClusky says for elite athletes today, pushing boundaries and breaking records is all about "the aggregation of marginal gains."
152 million Americans are expected to hit the stores this weekend and many of them started lining up late on Thanksgiving day for Black Friday deals.
But Kelli Grant, senior consumer reporter for SmartMoney, says today’s bargain hunters may be too late. She says the best deals are probably already gone, because stores started offering them early in the week.
And Grant says, some offers were so quick, they were “blink-and-you’ll-miss-them” opportunities.
So what are the bargains still out there and should we re-name Black Friday, Black Week?
