Costco identifies the package as a member product and may impose quantity or delivery limits. Recheck the live listing instead of relying on an older price shown in search results.
Costco or a Specialist Stamp Store?
Costco can be convenient when you want a common 100-count package and already have the necessary membership. A specialist store may be more useful when you want a particular year, theme, book, sheet or roll. Compare the same postage category and individual count before comparing totals.
Five Checks Before Ordering
- Select the correct warehouse or delivery address.
- Confirm that the listing is USPS Forever postage, not a mailing accessory.
- Verify the individual count and booklet format.
- Check membership, limit, delivery and return terms.
- Compare the complete checkout cost with the live options on this site.
