Re: OT: App that keeps track of "Or Best Offer" auctions on eBay to tell you what a seller will accept.
I think those one of a kind opportunities still exist on eBay. To one of
the points made by Dennis, once I know what I'm looking for across a
variety of marketplaces (eBay, CraigList, the Facebook Marketplace,
ShopGoodWill.com, etc.), the first thing I do is research what that item
has historically sold for on eBay. When you search eBay for an item, you
can filter the search to "Completed Items." (as opposed to active
listings). The results don't just included completed auctions, but also
Buy-It-Now listings that were optionally enabled with the "Make Offer"
button. For those listings, you will never know how much was actually paid
for the item. They only show the Buy-It-Now price. The actual sale price
could have been the Buy-It-Now price, or something less. But, of the
completed auctions where there was actual bidding, you can see what the
winning bids were, and that's what I go by to get some idea of the current
market value of something.
Then, I start to scour all the marketplaces for that item. Sometimes, I end
up buying on eBay. Other times not. The most recent example of this for me
was a B&K 875B LCR meter. My eBay research revealed that they were selling
for $125-$150. I watched all the marketplaces (easier to automate for some
than others). On eBay, I set up an alert to let me know when their were new
listings for that item. Then, as those listings come up, if it's an
auction, I put that actual listing on my eBay watch list (click the "watch"
button on the listing). As the auction gets closer to ending, eBay will
send you notifications that it's almost over. Yesterday, after getting a
notification and as the auction was minutes away from closing, .... I had
it open .. and got the item for $64 (shipping included)
I followed this same technique with the Tek signal standardizer plug in
that I just bought a couple of weeks ago off eBay for calibrating my 7000
series scopes (acquired for $77.. including shipping).
If there's insufficient historical data, and you're patient, another trick
is to wait for one to come up for auction, and just watch it all the way to
the end to see what it sells for a couple of times. I put this exact
technique to use today for a nearly new Atomos Ninja V external video
monitor that sold for $594 with shipping. Now I know what the most I should
For Craigslist, you can use Google Alerts to notify you when the item comes
up for sale anywhere in the country. Just use "craigslist.org" as the
target domain in the Google Alert search string.
OK, hope this helps.

There are certainly a lot of people asking me to let them know if I ever
