Others' opinions will vary, but in my opinion unless you are a well-established seller, auctions are a complete crapshoot.
The
ebay landscape has changed drastically since I started in 1998. Back then there were no fixed-price listings. Everything was auctioned, and that type of buyer experience (waiting until auction end to know whether you won and how much you spent) was the norm. Fast forward to today, and
ebay is far less of an auction site than it is a shopping/negotiation site. Depending on the category, upwards of 90% of the listings are fixed price or fixed price with best offer.
The buyer of today is more used to making a buying decision NOW, knowing their costs immediately, paying, and moving on to the next hunt/purchase. Waiting up to 10 days to know whether you obtained the item, potentially tying up funds or forgoing other items that come up in the interim is NOT what many buyers like to do.
I have just over 8,000 feedback on
ebay, split almost exactly 50-50 as buyer versus seller, so I "sit on both sides of the table" so to speak. Personally, I spend the vast majority of my buying time searching fixed price listings for exactly the above reasons. My auction bidding is reserved for exceptional items or potential windfalls, not normal everyday shopping practices, because I absolutely hate being in limbo for 5-10 days. That's a personal preference, but there are many out there like me.
Getting back on topic, auction listings, viewer traffic, and participation, is WAY down from years ago. This is great for buyers, but not so much for sellers. Running auctions is a major risk if you have a certain amount you need to recoup. Starting auctions at $0.99 is a big risk for a low-feedback seller, depending on the quality of your listings. I would recommend starting items at a figure closer to the amount you need to get rather than $0.99. It mitigates some of the downside risk.
Another problem with auctions is timing, in several respects:
1. With a 7-10 day window, you are at the mercy of who is actually browsing and bidding during that period. If your item is highly specialized or esoteric, that is potentially a losing proposition if the buyer(s) you need aren't active that week. Remember, with an auction you need at least TWO interested bidders. One won't do.
2. Annual timing. Historically, summer months are an awful traffic period for
ebay, as people are out doing other things, on vacation, kids (or grandkids) out of school, etc. May through August is the worst time for auction listings.
Personally, I made the switch from auctions to having an
ebay store with fixed price listings almost 10 years ago and haven't looked back. I may not get "moon money" when two bidiots start duking it out over an item, but I am minimizing my downside risk. With an auction, the buyers decide what an item sells for. With a fixed price/best offer listing, the seller makes that decision. Different sellers will have different levels of risk tolerance. Mine is low, so I opt for fixed price.
Many sellers use both methods, a core inventory of fixed price listings, and then some weekly auctions to help drive traffic to their fixed price listings. I personally don't do it that often unless I really want to clear out some low-level inventory, as IMO auctions are a lot more work than fixed price listings.
Good luck!
