Particularly with Illuvitars and Illuvials, it would be beneficial for all parties if the illuvidex could provide notifications/alerts when a desired item has been listed.
I imagine the simplest way to implement this is for filters to be applied, then an option to ‘be notified when new listings match this search’.
Value for seller is faster sale and or better price. Value for buyer is easily finding the desired collectables without constantly checking the market. Value for stakers is higher Revdis due to a higher demand/price/turnover.
This feature would also help ensure the best price for rare items (holos, skins, blueprints). This assumes illuvidex will eventually offer Auctions (Normal and Dutch).
