Do I need to pay any money upfront?
One of the great advantages of dropshipping is that you don't need to make any payments for the products you've imported into your store until you make a sale!
When you do make a sale, you need to fulfill that order through the app. You pay our exclusive DropCommerce discounted price and it will be shipped directly to your customer from the supplier. Your profits are equal to the difference between the prices you sold those products for, and the discounted DropCommerce price you paid for them.
You will also need to pay the supplier their flat rate shipping fee, so make sure to pay attention to what they charge when you import the product and set your shipping prices in Shopify accordingly.
