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 automation, and giving AI permission to buy looks too much like a real person?

Seems pretty petty to me.

So scraping bots and “buy for me” bots are bad, but the incredibly annoying sniping bots are OK? That sure feels like a double standard.

I never understood why eBay set things up to enable sniping.

Many years ago, there was an auction site called uBid. They had the sane rule: Bidding is open as long as there have been bids in the past 5 minutes.

So the end date could be January 24th, 3pm, but if someone bids at 2:58pm, the deadline is extended to 3:05pm. And it keeps going.

You know, like how auctions in the real world work.

There is no need for that. They only need to implement a closing auction like stock markets. But eBay hasn't done anything since the 1990's except raise fees.

What's the point of sniping bots when eBay has automatic bidding? Counter-sniping is essentially built-in, if your price ceiling is higher then a snipers then you're guaranteed to win even if they bid at the last millisecond.

Establishing the price ceiling is difficult, though. You might arbitrarily set it as $23, but be sniped at $23.30. The sniper bot only needs to bid that small increment over your arbitrary ceiling.

Can you really say that $23 was your hard limit, or would you have paid $23.40? Unless you're buying something also available at retail, nobody can be that accurate in foresight.

Sniping removes the 'contemplation window' to reconsider your bid.

Meanwhile it's now 100% free to sell on eBay for non-professional sellers.

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.

Another eBay precursor auction side, onsale.com, had the same setup. The auction ended at X date/time or five or ten minutes (I forget which) after the last bid was made.

I've bought hundreds of things on ebay over the years and I've never understood the issue with "sniping".

Sure, I've been outbid at the last moment. Losing an auction is always a little frustrating. But if I was willing to pay that price I should have bid it myself. Feels fair enough?
