At 6 Figure Drop Shipper, we encourage all students to find products that are locally sourced from the country they are selling the product to.
For example, if you are selling products to Australia then you want your product to be warehoused inside Australia for faster delivery.
The best time frames for delivery are under 2 weeks.
2 weeks is often pushing it but that is to be expected during busy periods. You may get some complaints if it takes longer than 10 business days, but just stay in communication with your customers and provide the tracking number.
Anything longer than 2 weeks, eg; 3 weeks and more is too long and should be avoided at all costs.
