FP Mailing Solutions is a provider of postage machines and postage services. We used them for over 5 years. When it came time to cancel the contract, they said they owed us a refund but then did not issue the refund even after more than 10 phone and fax requests and after a BBB complaint. My advice is to use stamps, Endicia, or take your mail to the Post Office. Definitely do not use FP Mailing Solutions.
