This has to be the most common question / rant / observation on this forum.  

For me, January this year was up 14% year on year.  February through April I was well down, about 25% year on year.  Then we had an election, and the first interest rate lift and my sales were down even more.  Macro economics I think played a role, as did a major new product release within my category which (I believe) caused people to defer spending.  July and August have been record months, about 40% up year on year.

That's just my experience.  One small seller so make of it what you will.

I do think interest rate rises and inflation sent a shockwave through the economy, causing people to tighten their belts.  Then, when they realise the world didn't end, they start spending again.  My sales match that hypothesis but I am sure every seller had a different story

I'm always hesitant to call sudden fluctuations a trend, but at the moment I think sales will improve when iceberg lettuces fall below $5.

My sales have gone down and viewings and watchers,

I had stopped listing for a few months and started up again recently.

I found then things had changed .
