I'm too lazy to go to the post office--can I just stick a bunch of first calss stamps on my package?

Question

It's probably about as heavy as a regular letter, it's just a funny shape. Is this okay?

Answer 1

Unusual shapes (including square) are fine, but will cost more.

Use http://postcalc.usps.gov/ to calculate the correct amount of postage.

You can pay with any amount of stamps that adds up to at least the correct amount of postage.

Answer 2

USPS won't forward square envelopes. My Christmas cards

were returned.  Any other shape is O>K>

hgt  versus  width  must have confused some of the sorters.

Stamps are O.K.  -  if your oz.'s are a littlle heavy put on two

Answer 3

Well I once received a package from my dad with a bunch of stamps on it. He also works for USPS.
