I'm not sure how EBAY works, and I have been a seller on there for almost 15 years. Usually the 3 months leading up to Christmas are pretty busy, and the summers are very slow. In the olden days, when I was keeping listings pretty active, I could easily sell close to $2000 a month, but it cost a lot less to list and the Final Value Fees were a much smaller percentage, so I was comfortable listing things with low prices. Now the listing fees are higher and auctions pay FVF not only on the ending price, but also on the shipping. I am much less likely to sell anything for less than $15 because it just isn't worth the trouble. If I was only selling one item over and over, I could afford to sell cheaply because there would be no effort in the listing process. My items are all unique though, so the process of listing is a little more involved.
Strangely enough, this week between Christmas and New Years has been very good. I guess people are spending their Christmas money? I don't know, but I have had several higher priced sales. It seems like my auctions become much more visible in cycles. I won't have any sales for a week, and then all of a sudden I will get four items sold out of my EBAY store in one day, going all over the country. I try to keep a few auctions up all the time, and the rest is sitting in the store. Unfortunately, the store FVF's are higher than the auctions, even though the listing fees are less.
I have some really nice vintage items listed at ETSY, and when I find a vintage item I list it first on EBAY, then move it over to ETSY if it doesn't sell.
I also have quite a few books listed on AMAZON, and just wait on notification from them. There is no listing fee there, but they take a chunk for commission.
As I have been going through the boxes of books, I am finding that I saved some that may have been worth listing years ago, but are no longer worth the effort, so they are going out on Freecycle.
Slowly but surely I will get the house ready. Slowly. Slowly.
