Reviews from users

Cost-effective and easy

Stamps.com is one of the most cost-effective and easy to use systems out there. Postage is easy to print and they also give refunds. You just have to follow their easy guidelines.

Great customer service!

The representative was very helpful and professional even if it was my error.
- Lara

Stamps.com is worth it.

For us anyway. The Stamps.com / Pinnaclecart implementation remarkably speeds up the time needed to produce shipping labels. Just wish other shipping companies worked with them.
