Speedy delivery builds trust
The quicker your customers can receive an order, the more they'll trust you. Build on the success of mail-order companies who offer next-day delivery for a few dollars more than their regular service. Explore the overnight delivery options available to you as well as the various international destinations where you might have to ship merchandise. If you ship small items, you should be able to offer one- or two-day delivery to most destinations at a cost that will please your customers and still maintain your profit margin.
