Why isn’t the Anbernic RG476H part of the March Spring Sale?

I noticed Anbernic is running their March Spring Sale soon with discounts on a lot of handhelds, but the RG476H doesn’t seem to be included.

Does anyone know why?

Is it just because the device is still relatively new, or does Anbernic usually exclude certain models from sales like this?

I’ve been thinking about picking one up but was hoping it might get a discount during the sale.
