Postcard stamps are 34 cents.
(I wonder if that means the pre-stamped postcards from the post office are 34 cents instead of 30 cents? Don’t know.)
Oh, I read the 30 cents in the thread...at the Post Office. I bet that is an error and I need more money!!
I will check the USPS...should have done that before. Sometimes it is hard to navigate.
Thanks for setting me on the road to find out the correct amount!
