Just a note; the shopping cart acts…questionable between sometime around midnight (Utah time) and 1-2am. Adding to cart appears to work, but doesn’t change the cart. It then shows up later. It’s like the cart gets locked out for a while, and then all the activities get run against it once it unlocks. My current working hypothesis is that DAZ is running nightly jobs (probably calculating PA payouts, clearing sales flags, or something similar) against their database, and it locks the database or some part of it for the duration of the run.
It works pretty smoothly during the day (Utah time), but that doesn’t help if you’re TZ-offset badly from them, or your awake hours are uncommon.
