Shipping costs money; there's no way around it. However, there are a few things you can do to keep postage costs as low as possible. In addition, the U.S. Postal Service offers discounts that can save a business money on shipping.
Weight and Dimensions
Items should be packaged so they're secure, but don't overdo it. Using heavy packing materials or boxes that are too large can increase shipping prices. Package materials appropriately to save on postage.
Service Class and Bulk Discounts
The USPS offers money-saving shipping options for several types of items. Of particular note is Media Mail, which is significantly cheaper than First Class and can be used to ship items such as books, movies and recorded music. If your business mails a lot of letters or fliers at a time, consider applying for a bulk mailing license. While bulk mailing requires that you presort letters by ZIP code, it can offer considerable savings on high-volume mailings.
Buying Postage Online
Buying postage online through the USPS website can net your business substantial savings. For instance, the USPS offers a discount on Express postage and Priority postage if it is purchased online. In addition, purchasing online postage can also save money on services such as delivery confirmation and signature confirmation.
