The Deal Sources table is intended for listing the sources from which you have purchased all your deals. You can include various types of sources based on your purchases. For instance, marketplaces like Appsumo and StackSocial, Facebook groups such as LTDF (Lifetime Deal Fans), platforms like Gumroad or direct purchases from a company's website. Additionally, you can use the "Second Hand" source when you acquire a deal from someone else after the original deal has expired.
Feel free to customize and adapt the table to fit your own workflow. Don't forget to utilize Conditional Formatting in the table settings to assign colors or any other formatting preferences you desire. If this comment is no longer needed, you can go ahead and delete it.
