Lots of people on vacation and spending dollars on that, sales is usually bit lower in summertime, you also have lots of competition so suspecting your sales would always be relatively low.
Diversify would be my advice and maybe use the build in analytic tool to get better perspective on what people want and what is already available.
Take for example the dresser in your library, if someone types in dresser in the search field then he gets a big load of dressers, your dresser (as your new here) is probably gonna end up on last pages and few get to those, it would take to mush time. The motherboard same thing, good offerings in front pages, yours sits on last page. The robot arm also has some competition but your offering is not as easy to find, add key words robotic arm to fix that. Your electronic cigarette is in good position probably sold that one recently.
