Teespring is a free online platform that lets you create and sell over 50 kinds of products with no upfront cost or risk. Teespring handles everything, from printing to shipping to customer service. You set your own selling price for the items you've created and decided to sell. You keep 100% of the profit. Teespring makes its money by taking out their fee, which is included in the base cost of the product. For example, if the 'base cost' of a t-shirt is $10 and you set the selling price as $24, you would keep $14 in profit.
