My Save the Dates and Invitations will be in 6×6 envelopes and I know they require additional postage. What I can’t seem to find on the USPS website or anywhere else is exactly how much.
I’ll be weighing one at the Post Office once I get them, but I’d like to have an idea going into it what we’ll be spending.
Did anyone use these? What was your experience?

It depends on the weight with all the inserts, even the ink on the envelope weighs something but to give you an idea, my square ones were $1.05 which is a .44 cent stamp and .61 cent stamp.

Invites under 1oz that are square are 64 cents.

On top of the regular per ounce rate, I think it’s basically an extra 20 cents if you do a square envelope.
