Has anyone mailed their invitations with multiple vintage stamps? If I was going to go that route where can I find affordable vintage stamps in large quantities and how much would it cost compared to just current forever stamps, I know it depends on the weight of the invitations but lets assume its no more than 1 oz. I guess I could mix-and-match with forever stamps vintage low value stamps if it is over 1 oz. There just seems like so many things to consider. If anyone has done this, any advice is greatly appreciated!
Thanks so much!
