All of our products are print-on-demand. When you purchase from our store, Sellfy prints and ships the product on our behalf. You can read more about this here.
Although not guaranteed, we try to earn about $5 per item. Taxes are based on your location and will be added upon checkout. The reason behind those choices is to allow everyone to contribute around the same amount for each purchase, regardless of the item they chose and their location.
In theory, we could produce some of the items ourselves, but the whole process (print-package-ship) requires a lot of effort, and a more complicated business setup. Maintaining a simple print-on-demand store like this one, already takes a considerable amount of our time, and we would rather spend the rest to develop our project.
