The Nexus 5X was, frankly, overpriced from day one. The 32GB 5X was a scant $70 less than a 32GB 6P, the latter being a substantially better device in most ways. As such, the Nexus 5X was predictably the only one of the two to get a Black Friday / Cyber Monday price cut. Google dropped the price of the 5x by $80, bringing the 16GB to $299 and the 32GB to $349.
