We have terminated our postal rental and use USPS online. Pitney Bowes gave us a lot of grief to terminate our rental. Scare tactics about how bad using stamps were, all kinds of weird lines. Also, they sent us a lot of renewals and called us constantly to renew and our contract still had another 9 months remaining. Then they wanted to charge us $500 for a box to ship the machine back. It was crazy.
We setup a corporate account on USPS, put a credit card on it. Ordered a couple rolls of forever stamps and some 2 ounce and 3 ounce stamps for larger envelopes. We already had a separate mail scale and print out the mail costs from USPS.com.
No more fees. We are saving thousands between the postage rental and the postage charges to reload on the machine.
