Hm, there is a marketing advise to show the highest price first, and then when people see the price for what they need is lower... but I guess it might work in both directions.
This is known as the "Door in the Face" technique (basic psychology) but it only works well in person. Basically, you state the highest price and then say something like "but for your purposes, we could bring it down to X amount." This instills gratitude in a person and they think you are cutting them a personal deal if they don't know how it works.
However, for websites with no human interaction, you should always show the lowest price first as it instills the "upgrades are possible" mindset. I would also HIGHLY recommend putting something on there such as "pay for what you need now, upgrade in the future piece by piece as needs arise"
This is what I have done, I bought the basic package first for the (amazing btw) declipper and over time purchased what I needed. It's an amazing way of doing it and yea If I had seen the initial high price I would have laughed and closed the browser!
IMHO, suck them into the software first, and then let the software sell itself because it will
I personally use the declipper as a VST3 in Reaper a lot on drum or vocal tracks that were recorded too hot and sent by a client, so if ya'll could increase the sample size past 4096 to 8192 or higher for smaller FFT bins on high sample rates, there could be some real benefits there that should be easy to implement!
