Not so fast. What had been first-class postage has triforcated (sp?)
into three different rate classes, based on whether it's a letter,
small package, envelope containing "rigid object", and various
other factors which I haven't entirely figured out yet.
The first-class retail postage for a 3 ounce item might be
either $0.75, $1.14, or $1.47 depending on its shape and
rigidity.
