BOSTON (CBS) - Black Friday sales are already a huge success.

Sales were up seven percent over last year, according to ShopperTrak, which said buyers spent more than $11 billion on Friday alone.

That’s the most ever for Black Friday, the biggest year-to-year increase since 2007.

But cash could be a competitor for retailers.

A Western Union survey found that 83-percent of consumers would rather receive $50 in cash than a $50 gift.

CYBER MONDAY

And today is Cyber Monday and plenty of online retailers are offering big discounts today.

Best Buy is offering a $10 gift card with a $100 purchase.

Kmart is offering free shipping on qualifying purchases more than $49.

At Macy’s, free shipping is available on purchases greater than $75, but clearance items are 25-to-40 percent off.

And amazon.com is offering the Kindle DX for $259, down from a usual $379.

Online sales on Black Friday were up 26-percent from last year.

HOT JOBS

And what are the hot jobs in this cold economy?

One word – technology.

Salaries are expected to rise by more than nine-percent for mobile app developers.

If you’re a data warehouse analyst, salaries are expected to jump nearly seven-percent.

And if your expertise is in making the user experience better, your pay is projected to jump more than six-percent.

There’s also a demand for making websites safer.
