I once purchased a website for $50 that sold a package of one hundred and fifty five adsense ready websites. At first, I was skeptical, but I was confident that I could make it work. I invested a little bit of effort into it - you know, passing the link around forums and such, and before I knew it I had produced over $500 in profit by selling the package for $25 each. I expanded the site by adding a nice ticket system and helped people out a bit.
I also recommended some hosting companies, and earned about $100 from that as well. Then I had the idea of getting a friend of mine to print up a bunch of flyers about the website and I was going to travel to Philly or NYC and hand them out. The unsuspecting people looking to make money online would visit the site and make a purchase! However, I never followed through with that.
Either way, I ended up getting bored with the site and I sold it for around $100. Luckily for me, the guy that bought it never changed the PayPal button and I am still earning cash from it!
