How much does it cost to mail a standard greeting card from PA to HI?

As of my last update, mailing a standard greeting card from Pennsylvania to Hawaii using USPS First-Class Mail typically costs around $1.20 to $1.50, depending on the size and weight of the card. Prices may vary slightly, so it's a good idea to check the USPS website or visit a local post office for the most accurate and current rates.
