If you want the two second recap, I made about $3,000 gross. My estimate to final price for everything was shockingly off by only $5 (I was of course high and low on some, but in the end the total price was very close). eBay didn’t estimate nearly as well for me, but more on that later. One thing I didn’t realize was eBay fees have gone up significantly. eBay fees were roughly 8% and then PayPal takes 3% (my eBay fees turned out to be 10% because of second chance offers, original listing fees, etc.). If I were to do it again, I would figure out the ball park price by watching a couple auctions close. Then try to sell high or at that price through craigslist. If you don’t find a buyer at a good price, then go to eBay. Like my expensive lens sold for ~$1350, but after fees and such it was more like $1200. So going to craiglist, I could have listed for $1400 and taken a lower offer for more money than what I got on eBay. But sometimes you see irrational prices on eBay. I didn’t really see that much this time around though. But I’ll review that later.
But the high level summary, everything probably cost me around $6,000 when I bought it new. Everything sold for barely over $3,000. eBay took a little more than $300 of that. PayPal took a little less than $100. So I was left with $2600. Crazy when you think in the end you lose $400 for the privilege of the eBay market. I’m not sure it justifies the cost like I was mentioning above. I don’t know why you would think normal depreciation is, but the 40-50% seems about right to me. More details on an item by item break down below.
Before I get into the numbers game though, this next chart is meant to highlight how cool Google Docs are. It is pretty handy making these plots and charting the data. I don’t see why people need excel at home. But the data behind the chart is percent of final price over time for the auction. You can see all of them had a good uptick on the last day by about 25%. As most people already know, the action all takes place in the last two days. But it is interesting how some get bid up high early and just stay there for a while. And I’ll be honest, I was a bit worried about my 70-200 sitting at $280 with two days to go. But in the end, system worked out as expected.
Watchers is a good indicator of interest and how affordable your price appears to be. Toward the end it was interesting to see people dropping off since it was too high in their opinion. I was watching fairly closely the last day and people started slowly falling off during the day. But for most every item, there were the hard core eBayers that waited for the last minute to bid up items. That happened for mostly every item. So even when you are losing watchers, some of your watchers are still interested more than likely.

So for the first eight or nine days (I always do a ten day auction), the watchers was most significant to me. Then the last day, I think the views is the most important. The purple line (total) shows the total per day while the others show the overall total for each auction over time (so day five is the total views over five days for each item, but for total is the number of views on that day). First day is significant, then it goes into a lull just to spike the last two days. I don’t think it matters which day it ends, the pattern would be the same. But the final spike would probably be even higher on a weekend.

Also I was surprised how flat the price per day increase was. I think we saw before the big initial spike. Then everything was very flat at about $100. Until the depressing day of Sunday followed by two back to back $1000 days. This was of course mostly just my lens.

Removing the 70-200, a similar flat trend was still there with only the last day showing a spike. I imagine this is more typical.

Here is my final post on how eBay’s estimate fared. I’ll provide more details and thoughts on the why below.

The 70-200 price I was a bit curious about. There is a version II that replaces this one so I wondered if eBay was distinguishing between the two. Apparently not since mine also came with two expensive filters and ended up well below the target. I owned this lens for three or four years. Bought it for $1700 (not counting $100+ worth of filters) I believe and sold it for $1350.
My Nikon D200 was a little disappointing since I did include a good number of extras like an extra battery. But this is a six year old camera body. Bodies depreciate like crazy. This I bought new for ~$1700 and it sold for under $500. An ideal cycle for a body is to sell right before a new one comes out so you get top dollar for it. A friend of mine used a Canon 7D for eighteen months and sold it only losing ~$150 (there is no 7D replacement yet or on the near horizon like end of this year).
The Tokina 12-24 was a big surprise. This one has a newer version and I had no extras other than the filter. How and why it went above eBays target was a bit surprising. Maybe the non-name brand lens market is a little less informed to know the difference
I bought this for $500 and it sold for a little over $300 after three or four years.
The SB600 is no longer made by Nikon and there is a significant market for it. It sold over my initial purchase price (I paid $180 and it sold for $250. There were some extras with it, but it still would have sold for more just with the flash alone. Also as an fyi, you are not allowed to ship batteries. I had to switch to a new buyer when I couldn’t ship them and the previous high bidder wanted a ridiculous amount to compensate for not getting the rechargeable batteries.
The S90 took a hit from the target, but I imagine that was because the S100 was announced. I wasn’t really surprised by this. I had it for a year and bought it for $320 and sold for $160. Pretty significant hit. I was willing to do it because I wanted higher resolution video and a faster lens on the telephoto end. I now have the LX5 I paid $360 for (or an increase of $200) which is worth it. I hurried a bit in buying mostly because our little boy is turning two soon. So recording the memories and in high definition was worth it to me. I know not everyone would see it the same, but that was my perspective especially since I need a filler camera until I find a mirrorless body I want.
Vixia HF100 is three years old. We paid $600 I think and sold it for $200. I know little about this market (which I think is dying much like point and shoots).
The tripod eBay didn’t really have an estimate for since the legs and head are different combinations and I doubt you can find a comparable. But I bought them for $230 and they sold for $123. The craziest thing is the buyer paid for two day shipping which cost $80.
The 18-70 is maybe the craziest. I owned that lens for eight years if not longer. Ever since my lovely D70. It came as part of the kit and so I don’t really know the price. I think it was valued at $300 at the time. It sold for almost $150. But I made a lot more than eBay thought I would and there wasn’t much in addition to the lens.
The two backpacks were pretty disappointing. I thought people winning one of the above items would try to score a backpack cheap since the shipping was free for any additional items. I charged a flat fee of $20 per item for shipping (which was pretty accurate in the end). So I think for cheap stuff it prevents it from getting bid up much since that is the overall cost (even though I don’t get the money, you have to think relative to Free Super Saver Shipping and other promotions companies have). But the Micro cost $60 and it sold for $20 and the Computrekker cost $200 (at least it does now, but I thought I paid less than that) and it sold for $50. I owned the Computrekker for six or seven years and the Micro for two or three years.
