The device you were using was designed to accommodate the needs of the incidental mailer ~ not the pro bringing in major volume.

There are other postage payment practices you should learn about.

25 identical small packages is hardly "major volume". Since the APC is capable of printing stamps in an denomination, there's no excuse for omitting such an obvious function as "print N more like this one". Knowing the USPS, there's probably some silly regulation involved.

Yes, there is another "payment practice" I could have used: taking time off to stand in line during office hours at Christmas.
