I bet you are frustrated by the lack of information about spy cameras available on the internet. I sure was. There seams like there are just a few big companies who have blown their entire advertising budget to make a big splash. (This includes the X10 camera of the late 90s fame). Spy cameras can come in very handy to anyone who wants one (provided, of course, that they aren't used for nefarious activities). Spy cameras have tons of legitimate uses, and can come in especially useful for home security measures.
Here's how I use the internet to shop for a new spy camera.
1) Use multiple search engines to do your shopping. Just because something is featured on Yahoo doesn't mean that it is featured on Google and vice versa. A lot of the time, advertising bidders are very different on Yahoo and Google for the same keywords. Search different search engines to see different vendors selling on different sites.
2) Use specific shopping search engines like Froogle. Froogle is great because it allows the shopper to select among multiple different vendors who are selling similar products. Froogle is a shopping specific search engine that you can use specifically for your shopping needs. I've used Froogle on multiple occasions to compare and contrast the different product I'm looking for. If you can think it up, it's probably on Froogle somewhere. Spy cameras are certainly no exception.
3) Learn about the ins and outs of spy cameras. Spy cameras come in as many different forms as flavors of ice creams. You can find spy cameras that are basically disposable and spy camera systems that can cost over $1000. Learn all about them and the mistakes that people make when buying them. Points 1 and 2 above definitely can help you make a decision, however getting the real knowledge is what you will use to ensure that you get the best deal possible. Learn all about spy cameras and save yourself a bundle.
