I ship little phone accessories and have been using small bubble mailers and placing 3-5 stamps on the mailers. Is there a better and maybe cheaper way of doing this?
Which country/state are you in? What weight is it that you are shipping, how often do you ship and what are the dimensions?
At that level you may qualify for a postage meter. I am not in the US, so I don't know the specifics. http://www.usps.com/postagesolutions/post_mtr.htm You may also be able to find a bulk mailing house that might be able to help you.
