How are your sales?

[singer_diecast]

I can't understand how my sales have bottomed out over the last 6 months. I usually sell around $2k -2.5k a month. 

I have renewed all my items through sell similar. I upped my store subscription.  I have added new product every day. And still my listing are not on any of the first couple of pages. They used to be on the front 2 pages. I'm so frustrated.  What the hell is going on? I was a too seller great feedback. And still nothing but crickets chirping!  I sell more on Facebook Market than this **bleep** hole!
