Obviously the first thing to compare is the price. When comparing prices on similar products, you have to make sure that the quality or specifications are round about the same on the products or services you are comparing. Its no use thinking that one piece of computer equipment is a better bargain than the more expensive one, as in that industry the more expensive item will be the better quality of higher specification of the two.

You also have to make certain of what your needs are. Let's take medical insurance as an example. If you visit the doctor maybe once a year for a cold, and you do not have any chronic diseases, it is really not worth it taking out full medical insurance. Rather in that case take something like a hospital plan, where you are covered in case of emergencies, and you are also covered for bigger operations etc. should it be needed.

When comparing products it's often a good idea to search the internet for reviews of the products. Often a product might look very good and is relatively well priced, but consumers have had many problems with it. Make sure you don't buy a cat in the bag, by reading up on the product that you are looking for, or are interested in.

Look for some kind of directory site. Although some of the products are being sold in an affiliate program, a lot of these products can be easily obtained online, and at a certain percentage discount because when you order products etc online, it cuts out a lot of administrative costs!

Happy shopping!
