SE might have calculated interest poorly. They probably settled on a price based off expected interest verse profit off investment. They might actually make more selling the items for a lower price.

I feel again I should probably point out, since it was on that list of options, Sub fees don't pay for the development of Cash Shop exclusive glamours. The sales of the items on the cash shop pay for the development costs. If they weren't on the cash shop, we wouldn't have gotten them ingame at all. That is the reason we are yet to see a Krile coat glamour, despite demand. The person responsible for greenlighting development for Mogstation items wasn't sure it would pay itself off due to the fact the Krile coat is technically challenging to adapt for other races.
