I recently spoke to a rep at a well-known Microsoft Partner; apparently it can be purchased for around $300, including 4 inexpensive CALs necessary to round out the order (5 licenses are required if you don't have an existing volume license agreement):
LTSB means no WSL, no Hyper-V, no support for VStudio neither for Windows SDKs (which refuse to install or don't install cleanly), so it's not for "developent" anyway.
