Yes, the things you send will be one expense, but dont forget to consider the cost of postage. Having a penpal can be very costly.

Is having a pen pal worth it?

Having a pen pal promotes many key skills, including reciprocation (a letter filled with all me and no questions does not make for a good pen pal relationship!), empathy and mutual concern. It also fosters the ability to search for and find common bonds, a key element of true friendship.

How much does it cost to send a penpal letter?

When sending a regular one-ounce letter via First Class Mail, you will have to pay only $0.55 for the postage, which is affordable. If your letter is larger or heavier or if you choose a different mail class, the postage price will be higher.
