Let's start with Amazon. It sells just about everything these days, so credit on the site is practically as good as cash. And there are two deals on tap this week that can get you a hefty amount of free Amazon credit.
• The first is a deal on the upcoming and much-anticipated Windows 8 operating system. When you preorder the Windows 8 Pro upgrade through Amazon for $69.99, you'll get a $30 Amazon promotional credit. The deal is good on preorders placed through Saturday.
Note: you won't get your credit until 30 days after the software ships -- presumably so you can't return the software within the 30-day return window but keep the credit. Also note that the Amazon credit cannot be put toward Kindle books, MP3s or video rentals. And finally, if you don't mind downloading the new OS right from Microsoft, rather than buying a physical copy, it only costs $40 to upgrade (from Windows 7, Vista or XP) -- which is the effective price after the Amazon credit is applied.
• If a $30 Amazon credit isn't enough for you, how about $400 Amazon credit? The SmartBalanceTransfers.com blog points out that that's exactly what you can get when you sign up for a Chase Sapphire Preferred card, now that Chase has started allowing customers to redeem their rewards points for Amazon credit. The card in question gives you 40,000 bonus rewards points when you sign up and then spend a minimum of $3,000 with the card in the first three months.
• Facebook wants you to protect your computer, so it's offering a variety of antivirus programs for free. Freebies on offer include six months of Kaspersky PURE Total Security, Panda Security 2013 and McAfee Internet Security 2013. The only catch? You have to "Like" the Facebook page of whichever antivirus company you choose, which shouldn't be too much skin off your back.
• Most of the time you have to buy something to get a freebie bonus, but Verizon is offering some free movie rentals just to hear them out. Visit this page on Verizon's website, check to see if Verizon FiOS is available in your area and listen to the sales pitch, and Verizon says it will send you codes for six free Redbox rentals -- regardless of whether you actually sign up for FiOS. The codes are good through June 2014. Keep in mind that you'll still have to pay late fees if you don't return the DVD within 24 hours.
