Well, sometimes the price jacks up a lot, but this might have some reasons:
- Us Europeans have to pay ~20% import tax on the whole price ( (Board + shipping + whatever fees) x 1.2 = final price ) so for me it's from 444.98 up to 529.52 just to get it
- Most boards are built with switches (some $60 or so, sometimes way more) and stabilizers and lubed and time for soldering, sometimes you find unbuilt sets
So yes, there is definitely a markup but most of it has its reasons
