Ever since work from home ended and the cost of everything started going up via gas prices and inflation, sales have been down. I want to say that was roughly 2 months ago.
I keep an eye on different sellers who sell in my same category (media), and it looks like all sales are down. You're mostly selling games, media, and smaller collectibles.
Unless you're selling something that has huge wide appeal, it takes quite a high volume of listings to produce sales. If someone is selling 10-20 percent of what they list every 90 days, that's a pretty solid turn around. Just looking at your active and sold listings, you have listed about 500 items with only about 20 sold. So that would be a bit of a cause for concern, but it's also a very small sample size. My advice would be to look at the kind of stuff you're buying to sell, and try to re-evaluate or learn more about what kind of items move or work to re-sell from whatever your source is. Based on the type of items you're selling, I assume you're getting them thrifting or from garage sales. (Unless it's your own personal stuff, in which case, ignore that advice).
Lower prices, run sales, liquidate stuff in lots via auction, etc. Maybe liquidate some stuff just to get some momentum going and have some cash flow, even if you lose a bit of money per item. You have nearly 200 video games for older consoles. Put some of the more common games together in lots.
Try to lot up things like your Fingerlings. I notice you have three for sale. Each cost over 20 to ship in Canada. Even if you offer combined shipping, the seller may not know that you have multiple Fingerlings in stock, because they are going to find your listing by searching all of eBay, not searching your store. Right now, you're charging almost $50 a Fingerling because of shipping, if you put all three together in a lot, you could charge $60 BIN + the same shipping price (since the weight/size won't increase much) and all of a sudden you're offering a much better value (80 for all 3 instead of 40-45 each).
I'd also consider going through your inventory and figuring out creative ways that you can sell things lettermail. For example, you could sell the Monster DVI cable you have new - open box with the paper packaging and the cable. If you remove the hard plastic, and lay the cable flat, it would qualify for lettermail, where it would cost under $5 to ship. Someone who wants the cable won't care about the hard packaging. You've now lowered the shipping cost by almost $20, meaning you can sell the cable for about $15 instead of the $35 shipped to Ontario I am seeing now. You likely have more items you could apply that line of thinking to. Even if it means selling them used - like new rather than brand new, there are certain items where cutting $20 off the price and selling used - like new will do better.
Just think outside the box a bit in how it relates to pricing and shipping. Like with your package of 10 CD-RW's. If those have been sitting there for $45 shipped (25+shipping) forever and not selling, maybe you could sell them as a quantity listing and list 10, each at an individual price, shipped via lettermail.
Also, go through the time to re-price your items. At 500 items, it wil take an hour or two at most to see what other people on eBay offer for them. An item that might have been competitively priced a few months ago can end up overpriced if the offerings change. What I started doing with my inventory last year was give everything a custom sku that tells me the month and year it was listed in. While a majority of the lower priced stuff I list sells within a year, there are items that are duds. This way, in terms of accepting or declining best offers, or re-pricing items, I know roughly when an item was listed. If someone offers me 50 percent for an item I listed this month, of course, I am not going to accept that. If someone offers me 50 percent for an item tha was listed in January of 2021, I am going to accept that because clearly I either should have never listed that item, or I did a bad job pricing it in the first place. You don't make a cake without cracking a few eggs, or however the saying goes.
In short, I'd find ways to get things selling, even if you don't turn a profit on the items. Just to get cashflow. Ask yourself, with what I know now, if I had the chance to buy that item to re-sell today, would I do it? If the answer is no, then liquidate it. Even if the answer is yes, maybe consider liquidating some stuff just to get some momentum going with sales, and to open up some cash/space if you're running your eBay store out of your home.
