Just to be clear, it was the Postage Resellers Program that Stamps.com used to juice its earnings. That program was ended by USPS as it was being widely abused primarily by Stamps.com and its subsidiaries. Stamps.com could still qualify for Commercial Plus pricing but that program is far less lucrative for them and would require them to offer exclusively USPS products and services . They would have to stop offering UPS and FedEx shipping to their customers.
