"The sales data has been really bad over the past two weeks"

Are you saying that you have not received any reports or information about how many sales and the dollar amount that you have sold, OR do you mean that you have not had any sales?

Those are entirely different questions. Amazon has tons of information about sales numbers, ranks, whether you are up or down for a period of time, and more. If you are not getting or can't access that data base you may need to ask for technical support.

If you just mean that there are no SALES, that goes with the territory on here from time to time. Every seller has periods when sales are slow to nonexistent. Just do a search to see people posting about not having sales for a week. There are some large volume sellers complaining about not having any sales in AN HOUR!

At the tail end of the year there were posts about sellers being down 80% and more from the prior year. Last year the Chinese sellers had OVER 50% of all sales on Amazon for the first time. Jeff Bezos sold out all US based sellers to try and gain a foothold for the Amazon site in China and it failed miserably.

It is not likely to get any better as they just opened their new side hustle to compete with all the cheap junk by having it on their own site.

Frank Sinatra way back in 1969 recorded "My Way" with the lyrics

"And now, the end is near

And so I face the final curtain".

It's getting to be that time for Amazon.
