Dropshipping is a business model where the retailer (dropshipper) doesn't keep the products in stock but instead transfers customer orders and shipment details to the manufacturer or wholesaler (supplier) who then ships the products directly to the customer. While dropshipping can be a profitable venture, success depends on various factors such as product selection, marketing strategies, supplier reliability, and customer service. Regarding Invastor, it seems you may be referring to a specific platform or website, but no widely known dropshipping platform with that name exists. However, I can provide a general answer based on the dropshipping concept.
