School Bus Additional Ounce Sheet of 20

These self-adhesive stamps are issued in sheets of 20 and maintain value equal to the current domestic additional ounce postage price. They are designed for easy application on larger mailings and can be combined with Forever stamps for multi-ounce letters. The USPS branding emphasizes reliability for teachers, students, and celebration announcements, making them a practical choice for bulk mailings related to school events and seasonal greetings.
School Bus Additional Ounce Roll of 100

Offering a coil of 100 stamps, this product supports recurring mailings that exceed the first-ounce rate. Like other additional ounce stamps, these will always reflect the current required surcharge. The coil format can be convenient for offices with high-volume mailing needs or for educators coordinating classroom communications and announcements.
School Bus Additional Ounce 40 Stamps (2 Sheets)

This package combines two sheets of 20 stamps to total 40 stamps suitable for small to moderate batches of heavier mail. The stamps’ value aligns with the current additional ounce rate, and the self-adhesive design simplifies preparation for classrooms, clubs, or community groups sending larger letters or announcements.
2017 Uncle Sam’s Hat Additional Ounce Sheet

As a classic decorative option, this sheet of 20 additional ounce stamps remains a reliable way to cover each extra ounce when mailing. The stamp’s design is tied to early USPS issues, which can be appealing to collectors while also providing practical postage assistance for two-ounce mailings when paired with a Forever stamp.
2017 Uncle Sam’s Hat Additional Ounce Coil

This coil of 100 stamps mirrors the sheet option in purpose: to cover the additional ounce rate for heavier mailings. With a Forever stamp for the first ounce, these stamps provide the necessary increment for the second ounce and beyond. The coil format is particularly suited for organizations that mail frequently.
School Bus Additional Ounce 2 Sheets (40 Stamps)

A compact option for households and small offices, this set provides two sheets of the additional ounce stamps. It’s designed to ensure that a batch mailing—such as school announcements or event invitations—can be prepared without needing frequent restocking. The stamps are aligned with the current surcharge and work alongside Forever stamps when mailing beyond the first ounce.
Celebration Blooms Forever Stamps (Sheet of 20)

The Celebration Blooms Forever stamps offer a decorative option for any first-ounce mail. As Forever stamps, they remain valid for the current first-ounce rate, providing a versatile choice for seasonal greetings, invitations, and personal correspondence. While not an additional-ounce stamp, they pair well with the additional-ounce stamps when mailing heavier letters that still qualify for Forever pricing on the first ounce.
Buying Guide: Key Considerations for Choosing Additional Ounce Stamps
- Compatibility with Forever stamps: The primary purpose of additional ounce stamps is to cover the increment beyond the first ounce. Ensure you have enough Forever stamps for the first ounce and add the additional ounce stamps to reach the correct total postage for your mailing weight.
- Format and convenience: Sheets, coils, and rolls offer different convenience levels. Sheets are handy for smaller offices or classrooms, while coils are ideal for high-volume mailing environments.
- Visual appeal and occasion: Some stamps feature decorative designs (like Celebration Blooms) that suit invitations or special events. Consider whether a design should be purely functional or also visually appropriate for the mail’s purpose.
- Rarity and collectibility: Some stamps (such as Uncle Sam’s Hat issues) have collector appeal. If you value mint conditions or vintage aesthetics, this can influence procurement decisions, though it should not affect postage value.
- Cost-containment strategy: If you mail frequently, a mix of Forever stamps for the first ounce and additional ounce stamps for subsequent ounces can optimize the cost per letter over time. Track rate changes to adjust supplies accordingly.
- Storage and handling: Keep stamps in a cool, dry place away from direct sunlight. Protective sleeves or dedicated containers help prevent damage to adhesive surfaces, ensuring reliable postage.
- Usage planning: Plan for typical mailing weights (1 oz, 1.5 oz, 2 oz) and create a standard process for applying stamps. Clear labeling (e.g., “1 Forever + 1 Additional Ounce”) can reduce misapplication.
- Reseal and repackage considerations: If using sheets or rolls for classrooms or offices, label by weight category or event to simplify distribution and ensure accuracy during mail preparation.
Overall, selecting the right combination of additional ounce stamps and Forever stamps supports accurate postage for heavier letters, while optional decorative designs provide a personal touch for invitations and announcements. By understanding format preferences and weight needs, you can optimize mail preparation for school, community groups, and home offices alike.
