There are a lot of items that can be purchased very inexpensively at garage sales or thrift stores and sold for higher prices elsewhere. A few years ago I discovered that I could purchase good hardcover books at my local thrift shop for $1 or less.

Tutors are in high demand whether it’s online or offline. Therefore, if you’ve got a brain and like helping others use theirs, become an e-teacher to earn an extra income in your spare time.

Sites like Tutor.com and TutorVista are places you can sign up with and build a good reputation over time as a coach. If you’re really good, you can conduct lectures, seminars, or webinars that are transmitted online. University and college students are always willing to pay money to gain access into highly-respected online webinars.

Pay-per-click advertising is the easiest way to get traffic to a brand-new site. It has two advantages over waiting for the traffic to come to you organically. First, PPC ads show up on the search pages immediately, and second, PPC ads allow you to test different keywords, as well as headlines, prices and selling approaches. Not only do you get immediate traffic, but you can also use PPC ads to discover your best, highest-converting keywords. Then you can distribute the keywords throughout your site in your copy and code, which will help your rankings in the organic search results.
