It's one of the issues with balancing timeliness of reporting the deal and how marketplaces work. If I put all my keys up online, undercutting the competition, the system will automatically want to report that a key is available at that price. But that really messes up how tracking this stuff works.
I was just contemplating this and while I have no say in the matter, I can see how hard it is to manage this. If you delay reporting, people will miss actually good and timed deals. YOu're always going to have a lead time which delays the alerts regardless, but that would cause even more delays. I dunno if this can be fixed.
