Some form of this (without AI) has been practiced in the past. How does one get around this?

Remote hosted disposable web browser instance and add items to non logged in cart then login once you see the prices so the offline cart is merged to your account?

Does anyone know a reliable method?

No because the pricing is based on the perception of actual person/distinct (lived) personality. It's hard to capture these things in a purely headless way. You need to feed realistic sensor(wifi/bt/mic) data + location data (gps + wifi) to get accurate ads.

Without doing anything illegal and without broadcasting your intent on trying to espouse something criminal maybe pretend to have an affair (and encourage others to pretend to do the same or similar).

Separate communication apps on disposable visa, different google playstore account, different phone number, etc#. Trust that wifi+bluetooth+cellular proximity will link the phones together.

After a few weeks-months that second phone should be the similar enough to their actual profile for you to setup a remote residential proxy (w/ effective split tunnelling setup) for other people to funnel unique but similar requests through.

It's also depends on where you come from. The price if you go to the airline's website directly may not match what you'd get off you come in via http://flights.google.com or http://expedia.com or http://kayak.com or whomever.

I saw a post on the eBay subreddit from a seller regarding shipping. They looked at the price to ship the item through eBay, popped off to a third party shipper to price compare- when they came back to eBay it quoted a new lower price.
