Probably the cheapest so far for the refreshed Spectre X360 with an 8th gen Intel CPU. From memory, the regular price of this model at JB is $2199 (I remember because I've been tracking the price of this notebook for a few weeks) so the current price is around ~22% off.
The i7-8550U/16GB RAM/512GB SSD (13-ae010tu) is also down to $2293 with their current 15% off computers deal.
