The online feedback to a dis reputable seller would stop most buyers from giving him money. I sell vacuums, so let's use that as an example. But there are times when saving a few dollars by shopping online isn't in your best interest. The problem is, there are sellers that obtain these vacuums from legitimate dealers that are going out of business. Some vacuum cleaners are more expensive, made better, and are in more demand. I'm using vacuum cleaners as an example, but this idea applies to many kinds of product.

So the online method of buying pretty much patrols itself. These vacuum cleaners are designed and built to last for many years, even decades. These vacuums are ones you would maintain and service to ensure you get your money's worth.

Some brands of vacuum cleaner are inexpensive (under $150), and you are not out a lot of money if the product proves defective, and you cannot get a replacement. These are not disposable vacuums.

Buying online is a way to save money, and nearly all online dealers are reputable.
