Lol please. The market is healthy when it comes to items that are worth selling. Old items that are useless or for vanity have lower sales unless it's a really new item (PJs) or a trend is going on. Prices also fluctuate and bounce back up to the original pricing unless there is a change in demand and supply.

Here's a three week sample of my 3 month data of the Water Cluster Market.
