Using GS 7.0.4 for Mac Yosemite.
I want some listings to offer a Flat Rate Envelope for $6.45 as listed on the USPS site, but all the Flat Rate Envelope choices #0 thru #6 (and the one unnumbered before #0) all say $5.80, which is the old price. If I choose “Calculated,” I’m afraid the cost will be higher since it’s not using the Flat Rate envelope.
What exactly do the different numbers after “Calculated” and “Flat Rate” mean, even those that have the same price?
Couldn’t find this addressed before but feel free to offer a link if it has. Thanks!
