Where have all the buyers gone?

Scratching my head a little, and wondering where all of the buyers have gone? My last selling week 09-15 March is the lowest sales week I have had in the past 6 weeks. Prior to this, every prior week had been great. My sales fell off a cliff from 9th March.

I'm pondering two things, the 10th March was the implementation date for Trademe's recent changes to casual sellers (I'm in-trade), but it also coincides with a period of uncertainty surrounding the iran war and petrol prices/higher living costs.

Hard to determine the exact cause of sales falling off a cliff. I only hope that Trademe are closely monitoring the sites performance, to determine whether its recent changes, or sentiment which is causing a drastic drop in sales.
