It might be a lot less exciting and might not make sellers happy, but it's a lot more efficient and fair for everyone in the long run. Just set a snipe for your one and only final price, then walk away - don't check up on the auction, don't change your snipe price, don't do anything. In my view, sniping actually fixes the flaws that come up when humans bid on eBay. This is intentionally made worse by eBay sending notifications whenever you're outbid and other tricks. The issue is that humans aren't rational, and they get emotionally invested in the specific auction and make our decisions based on sunk cost and FOMO. This means that for rational actors, the best strategy would be to always bid exactly as much as they value the item (make their first and only offer for as much as they're willing to pay), since they will pay only as much as others value that item. PPS(edit): I wasn't bidding on this item btw, just popped by to drop this comment and my $0.02 on sniping for anyone reading.Ĭlick to expand.Just since the subject of sniping came up, I wanted to add my two cents.Īn ideal auction is one that guarantees that the highest bidder will win, and they'll pay the correct price, meaning that they'll pay a price that captures the market rate in some fair way.Įbay uses second-bid auctions, which is a great auction mechanism in theory - bidders make their bids, highest bidder wins, but only pays a single increment over the second-highest bid.
#Gixen item id free
Don't know much about others but it's free and straight-forward to use (copy/pasta the auction ID# and put in your desired max bid and it does the rest). PS I've been using a web app called "Gixen" for it, for the past year or two. Users can go into their Gixen dashboard and change information or delete a bid at any time. So if buyers are constantly in the market for a certain itemeither for personal use or resalethey can set up snipes on an unlimited number of items. It seems that most serious eBayers use them, and while I don't consider myself an eBay expert or fanatic by any means, I really was sick of it happening. Bids can be entered on Gixen from the moment a listing is posted until it ends. The conclusion I came to after getting sick of losing auctions where I was placing an honest decent bid is thatĪ.) eBay allows sniping automation tools ī.) however I feel about it, I guess if you can't beat 'em, join 'em. The psychology of bidding does indeed seem to artificially inflate the price, so if you're a deal hunter (well, you're in this forum aren't you? hehe.) I would argue you should get on board the snipe-wagon if you haven't already. Lines | WriteToFiles(path=job_options.EBay sniping is an interesting topic. # the sink and uses it to write to a directory defined by the path This will be used by the WriteToFiles transform to write # Replace the following with your schema. This new sink is used like the following: import apache_beam as beam Self.writer = (fh, self._schema, self._codec) With the caveats out of the way, here is the work-around: from apache_beam.io.fileio import FileSinkįrom apache_beam.io.fileio import WriteToFilesĭef _init_(self, schema, codec='deflate'): Note that as of the writing of this post (), this method does not work with the Apache Beam Python SDK = 0.3.1.1 and Avro to >= 1.9.0, but be careful as this is currently untested. There is a work-around in which you define a new sink and use that with the WriteToFiles transform which is able to write unbounded PCollections. Finally, the WriteToAvro transform cannot write unbounded PCollections. PPS(edit): I wasnt bidding on this item btw, just popped by to drop this comment and my 0.02 on sniping for anyone reading. Dont know much about others but its free and straight-forward to use (copy/pasta the auction ID and put in your desired max bid and it does the rest). First, there was some badly formatted data with regards to null/None (you fixed already) and ints/floats (called out in comments). PS Ive been using a web app called 'Gixen' for it, for the past year or two. It looks like there were a few problems with your code.
