After you put down those bags after a weekend of shopping, it's not over.
Cyber Monday - the day when retailers say shoppers flock to the Web for holiday deals - comes tomorrow with its own set of mouse-buster sales.
Here is some advice to save money and stay safe while surfing your way as Santa.
Look for bundle discounts: If you're shopping online, look for bundled discounts, combining dollars-off and free shipping.
"It used to be there was one or the other," said Mike Allen, founder and "chief executive shopper" of Shopping-Bargains.com, a coupon Web site. "This year, I'm seeing a lot more of both combined: free shipping and 15 percent off a $100 order, for instance. They're 'double-incentivizing' you to buy."
He also recommends looking at the online minimums for discounts. If you're buying $65 worth of sweaters, for instance, it might be worth bumping up your order to $75 to take advantage of free shipping.
And try to group multiple orders from a single retailer, so you're only paying shipping and handling fees once.
Don't click on any links sent to you. Instead, type in the retailer's name or the Web site address yourself. "It takes a few extra seconds but saves you from potential identity theft or credit card theft," said Dave Marcus, director of security research for McAfee, the security software company.
Beware of "too good" deals. If they sound too good to be true, chances are they're fake. And look out for too-low prices on upscale, luxury brands like Cartier or Tiffany. Scamsters know that consumers are price-shopping, so be certain the Web site you're perusing is legitimate.
Beware of holiday cheer. Holiday Web sites surface every year, offering free downloads of Christmas carols, ring tones or festive screen savers. Aside from merriment, they often harbor malicious software that can infect your computer.
Beware of "phishing." It could be a phony FedEx invoice or a heartfelt appeal from a real-sounding charity. Official-looking e-mails, with company or charity logos, can pop up, asking you to verify credit card and other financial information. Even if you think the e-mail is legitimate, contact the company yourself to verify the request.
Don't shop in public. Avoid using open Wi-Fi connections while making purchases online. Use a secure network.
Update your security software. Don't assume it's being done for you. Click on your computer's security icon and hit "Auto Update" to be sure it's automatically updating with the latest protection against viruses and other gremlins.
Mix up your passwords. Don't use the same passwords for online accounts. Use a combination of letters, numbers and symbols.
Watch out for bogus job sites: There's also the seasonal flurry of fake job sites, offering "Earn More Money for Holiday Shopping," which Marcus said are often money-laundering sites for cyber-criminals.
