For example - http://landrick.react.themesbrand.com/ is 17$.
https://g-axon.com/wieldy-ant-design-react-redux-admin-templ... is 24$ (which uses ant design)
I bought this the moment I got the email about it this morning because this is going to help my productivity in building web applications. When you use Tailwind, you aren't using a pre-made theme as you would with a bootstrap theme you buy, you are designing it from scratch.
With this UI kit you'll get some nice building blocks to become even more productive, but you'll still end up modifying stuff to make it yours.
I honestly think this is priced too high.
Not only that, but I think the pricing model is wrong; lifetime access for a one-time fee is a big mistake (and one I previously made with a startup).
As a developer, I understand that you need a predictable, repeatable income stream to keep going - and if I'm going to invest in something like this, I want it to keep going. I'd far prefer to pay something like $49/y instead of a one-time $249 fee.
