Somewhere in Small Business Opportunities it will state they are not responsible for any claims made by the advertisers. Spend the time to analyze the mail order products and services you are considering purchasing. Send them a small order OR write them a letter. If they don't respond when you have taken the time to enclose an SASE, they won't provide good customer service. I've read horror stories of people who tell about their rip-off experiences.
Some people even admit to having been ripped-off several times.
While there are many legitimate reasons why someone gets ripped-off, the majority of them can be avoided by using common business sense. During the last several months, a lot of dealers have complained about the new kind of rip-off artist. This person runs an advertisement in a publication offering a certain item. When the customer responds, what they receive has absolutely nothing to do with the product depicted in the original ad. If you get angry and write a letter back to them of your complaint, normally the advertiser will not respond.
