This question comes up a lot

Global Forever Stamps are currently worth $1.15. Whether you buy the 2015 design or an older design, the value will be the current selling price.

Thanks for that. Did a search and discovered they're worth $1.10. According the USPS website, postage for a 70g c5 envelope is $3.12 so three would be fine, but when it's specified that the envelope is rigid, the cost changes to $3.33, leaving it 3c short. Anyone know if this matters? I'd assume they're strict with the cost and don't have any flexibility.

edit: According to the USPS website, they're actually only worth 49c - "The Harry Potter™ Forever® stamp is equal in value to the current First-Class Mail® one-ounce price, which is $0.49." So seems like three definitely won't be enough.

Appreciate the help, just want to make sure I get everything right before I order things.

put 3 of these stamps on your self addressed envelope and you'll be set!

That looks like a perfect solution! Couple of questions if that's okay... Would they definitely be okay to use? I'm never sure about novelty stamps, although I'm sure I'm just being paranoid.

Do you know their value? I zoomed in but couldn't see it printed on the stamps.

Thanks very much!
