OPE as written in the past in support of lesser-known mailing services such as Media Mail and Parcel Post. Our readers' thank-you cards tell us how valuable this information has been. Today we would like to remind readers about their First Class Mail options.
For packages over 13 ounces that do not contain media such as books, CDs, or 8-track tapes (for which you would be an idiot not to use Media Mail), Priority Mail, though a ripoff, is your best (and only) rate. But First Class Mail Package is always your best rate for packages under 13 ounces.
Say you want to mail me your unused prescription p@in killers. Let's compare the rates for an 8 ounce package:
Priority Mail: $4.95
First Class Mail Package: $2.41
As you can see, Priority Mail is a huge ripoff.
What about delivery time? you ask. Priority Mail claims (but does not guarantee!) a delivery time of 2 days, but USPS admits that
there is no separate service for Priority Mail, in other words, Priority Mail is treated the same as First Class. Shocking? You bet.
Here at OPE, we have a small postal scale and a collection of stamps in various denominations (available from USPS.com) so we can frank all our mail easily at home. FYI: Packages under 13 ounces can be mailed from your neighborhood drop box.

Use Priority Mail only for cats over 13 ounces
