Postage for stamps

I went by the post office today to have them weigh my invitation so I can find out how much the stamps will cost. I mentioned to them it's a wedding invitation. First the lady told me something like $1.17, and I was rather surprised by that. Then she was like oh no wait, I'm sorry $1.00. I was like wow really. She told me it goes according to the diameter of it these days and not really the weight or something like that.

I think I'm gonna go by another post office for a 2nd opinion because I just did not feel confident in what this lady was telling me. But on average, what are most people paying for the postage per envelope? I know my invitation is big, but I don't think it's anything crazy or out of the ordinary from other invitations I've received.

we paid $1 per envelope ....i didnt budget for that!

but i checked a couple different post offices and they all said they same

plus the inside envelope


so it was about 1.50 for each one

Also make sure if you DIY that you have the RSVP enevelope measured. I know we automatically thing it's 42cts but my friend did hers & envelope was alittle larger & she had to pay 59ct for RSVP.

My wedding envelopes were 59cts
