A: Yes. They are authentic USPS issued postage. All of our postage undergoes a series of tests for authenticity, and is money-back guaranteed to our customers.

We have aided law enforcement in several fraudulent and counterfeit postage cases over the past years, and have direct access to an inspector agent representative specializing in such cases.

A: Yes. There are no laws or regulations prohibiting the buying and selling of second-hand postage for less than face value. Just ask a stamp collector.

A: All of our postage is in complete sheets, books, or rolls. Unless otherwise stated, they are unfolded and in post-office-fresh new condition, ready for resale.

A: No. We can sell our postage to anyone as long as their purpose is to use the postage to mail items.


A: Yes, these are Forever Stamps so they will always be equal to the value of one ounce, first-class letter in the U.S. The stamps can be used to mail a letter, or towards the total postage cost of any US-PS shipment, or can be saved as a collectible.

A: Yes. We accept returned items within 14 days from when they were confirmed delivered. We will provide a refund in full for all items that are returned in the original condition in which they were received. Please read our Terms & Conditions for more information about returns.

A: Once you place your order we will hold your items for up to 10 days to allow you time to make your payment. If no payment is received within that time, you will be notified and the items will be relisted in our store. If your payment arrives after we’ve relisted your items and they are no longer available for sale, we will return the payment back to you.


A: It depends on your payment method, and when you send it.
All orders will be put on hold for up to 10 days from the date the order was placed until payment is received. Your items will be removed from our website and will no longer be available for sale to anyone during the holding time.
Once payment is received by us, we require an additional holding time from the date it was received to allow for the payment to completely process and clear. Payments by check will require up to 4 business days.
