If you didn't buy them from the USPS and you paid a "bargain" price you get what you paid for. By now even remote tribes in PNG know about the counterfeiting problem.
The original price was the cost of a 2023 Freedom Forever stamp times however many you purchased. You have to know what you paid or can easily look it up on
Amazon. I have never heard of
Amazon selling overstocked or returned postage stamps.
Something smells like old fish.
