Tried selling on eBay as a regular Joe lately? Item sold for roughly $190 and I lost $45 in fees - I didn't even have a premium ad or pay for any of the boosting. No wonder Facebook marketplace has destroyed them

At least in the UK, I don't lose any of the selling price to fees, 0%. The buyer has additional buying fees on their side and postage is included in the final price.

Even if they use Paypal?

But if that someone isn't rational it is better to not give him the time to react to your highest bid. Also some sellers seem to use some fake accounts to bid high on their own item, revealing your max bid, then cancel their bid, then bid right under your max bid to maximise their sell price. Happened to me twice, and now no longer setting my max bid in advance since.

What were you buying?

Mostly electronics, SSDs, motherboards, etc.

There are 9 time zones in the US and depending on what your buying in the eu, jp, etc, I'm not going to be up to deal with the end of an auction, either too early too late or you know I have a real efing job and i'm doing something. Having ends of auction require you to be around means you lock out large parts of the market.

...that's what auctions are...being around to bid...

Except for sealed bid auctions. EBay doesn't do sealed bid auctions, and that's fine.

This how Trade Me (NZ auction site) works: any bid in the last 2 minutes delays the close time to 2 minutes after the bid. That can happen repeatedly, and I've seen it go on for over 20 minutes on highly contended auctions. It works well.

It doesn't need to!

If the winner, instead of paying what they bid, pays what the second-highest bidder bid (and bids are secret until someone exceeds them) then the incentives change. Everyone is incented to bid what it is worth to them, safely knowing (1) they won't pay more than that, (2) they will win the auction if no one outbids them, and (3) they won't pay more than necessary to win the auction.

eBay works this way (more-or-less), so you CAN (if you choose to) simply place your bid any time that is convenient and then ignore the timing of the end of the auction and all the sniping bots.

The problem is with items that have a national market but not a local one. For example - there may be very few local buyers who will pay a decent price for a vintage slide rule, but many on eBay. My general strategy is to list on FBM first for the eBay price that I hope to get, and then accept offers down to 75% of the price. If I don't get any bites after about a month I switch to eBay.

This. I was selling an obscure book once. I doubt there is anyone local that would be interested in it. It was sold on eBay within a week.

Same for a half functioning Xbox. No "normal" person would want that. But apparently, on eBay, something like a dozen people took serious interest in it, and it was sold in a few days in "parts only" condition. For sure I didn't like how much the transaction fee I paid, but at least I got rid of it for a decent amount of money.

What is the use case for LLM agent shoppers? I can't imagine delegating the purchase of a used item to an AI (I'd be okay with AI identifying the best deals for me to review). This must be something for people who are doing something at scale like flipping items on Ebay or drop shipping. I imagine this type of automation existed before LLM agents came along - what do they add? Is it just the ability to evaluate the p…

"Hey, ChatGPT/Grok/GeneriBot4000, please watch for a great deal on a 1982 stratocaster guitar - must be in good or better condition, $600 or less, and if you see it, go ahead and buy it without confirmation" Ongoing tasks, arbitrage for mispriced postings in ways that aren't currently exploited that LLMs make feasible - by banning auto-buy, maybe they're attempting to delineate between human seeming behavior and auto…

I have decent tech company salary but I don't even buy $10 books without checking everything. This week I almost bought a wrong book (manually) because how similar the title is. Automating stuff with AI is interesting, but I don't want the hassle of getting surprised and handling returns, if the item can be returned at all, especially on eBay.

Then just put your actual hard limit in as your bid, and sleep soundly, knowing that if someone pays $0.01 more, it's OK because you wouldn't have wanted to pay that anyway. I've never really been bothered by "sniping" in eBay. I always bid my absolute 100% maximum, and if someone bids more than me, then they can have it.

I don't understand this line of reasoning. I don't do auctions, but if I did, it would be because I want that item. When I want something, I never have an absolute hard price ceiling; if I'm willing to pay $10000, I'm willing to pay $10000.01. I can't imagine anyone who would be happy to pay $X for an item but not $X + $0.01. Like, if I'm at a store and an item costs $500, and I bring it to the checkout and the cashi…
