Dropshipping business is profitable. Just look at its market size of over $100 billion. If you carefully select your products, you can hit a motherlode and see enormous profits. On top of that, you will not have to pay for incurring running costs like most eCommerce sites would have.  The only cost you will have to take into account is building, launching, and hosting your online store. However, Shopify offers affordable pricing plans starting at $29 per month.
