"For TV's, the availability is great," Ramirez says, with retailers moving quickly to match discounts by competitors.
Here are some of the places that may be worth checking out, plus some shopping tips to consider:
• Newegg is advertising "Shell Shocker" and "Eggxtra" deals on computer hardware. In one deal, customers may find that an Android smartphone from Samsung (the Galaxy S Blaze 4G) is "free," if they're ready to sign up for a monthly service plan with T-Mobile.
• Kohl's says deals will flow "all week long," and offers an extra 20 percent off all purchases through Tuesday. For people who want towels or twill pants rather than a tablet, that's pretty attractive. As with most retailers pushing for online revenue, free shipping is also included.
• Amazon is selling its Kindle Fire (a blend of tablet and e-reading device) for $129, down from $159. (Enter "firedeal" at checkout.)
• Airline and cruise ship websites are offering Cyber Monday bargains for those ready to commit some time, not just their money. American Airlines touts prices as low as $58, one way.
