Not quite the same thing, but I used an LLM to cobble together a HTML file that allows me to search for products on Coles, Woolies, Aldi and Amazon at the same time in the same window (via frames and a Firefox extension to get around some security settings).

Works a treat when planning our big shops for the week, and has already saved us hundreds of dollars since Jan.

GTA6 is likely going to be the only reason I’d get one, because the rest of the exclusives have been pretty lacklustre.
