We have never provided LightBurn license for $30.00 USD.
We do offer 365-days of access to updates and fixes, known as a license ‘Renewal’ for that price, but not for the original license key. I think this is a case of confusion around our pricing model. You are not being punished for trial, as we offer that to everyone for free.
Which site are you referring to here? LightBurn is already priced as low as we can, while continuing to provide high levels of value, support and continued development. We do not offer discounts, as you may be thinking.
