The Commissions Report table gives you information about your sales. You can see on what date they were created what type of plan was purchased, and the campaign from which the sale has originated. If you only refer clients with your affiliate link directly without using campaigns, you will see that in the column "default". The last 2 columns show what the status of a sale is and what commission you can expect for it.
The Associates Program is free to join, and we provide resources on the Associates Site to help Associates succeed with the program. We have never authorized any business to provide paid set-up or consulting services to our associates, so please be wary if any business like that (even one attempting to appropriate the Amazon name) reaches out to offer you costly services.
Affiliate marketing is commonly confused with referral marketing, as both forms of marketing use third parties to drive sales to the retailer. The two forms of marketing are differentiated, however, in how they drive sales, where affiliate marketing relies purely on financial motivations, while referral marketing relies more on trust and personal relationships.
