Guy makes a great point. Consider raising the price. Perhaps offer first year of support for free to people who bought hardware from Start9 and then give them a discounted rate for year two and beyond. Even if you don’t change the support membership to an annual subscription, consider pricing the lifetime membership in sats, so you at least can keep up with inflation. It wouldn’t be unreasonable if you priced it at and kept it at 15,000 sats for a lifetime membership.
