[feature] Parse JSON in www.coles.com.au pages

[CRCinAU]

Version and OS
v0.50.2 Docker

Is your feature request related to a problem? Please describe.
Coles gives JSON for price data etc which CD completely ignores. This would be much better than trying to parse the HTML.

Describe the use-case and give concrete real-world examples

I've seen my Coles price trackers, which used to work, are now showing an error in the UI of:

Cannot run, more than one price detected, this plugin is only for product pages with ONE product, try the content-change detection mode.

I don't know if it's because there's a "Customers also purchased" section at the bottom? I don't think that used to be there.

I'm also now running v0.50.2, though this has been broken for over a month. I'm not sure if the "break" correlates to any release of ChangeDetection, or if it was just a change on Coles' end that caused the problem.

Yeah - I don't think this is a CD change, but the Coles site. Mine broke quite a while back, but I didn't get around to checking them until recently. This was when I noticed the embedded JSON data.

hmm only one product there

Looks fine here

[CRCinAU]

My output for a number of products seems to be.... uncertain...

Could it be that for different areas, they have some different content? I know some have some 'related products' listed - but all have JSON present.

Well the link you supplied in the original issue works, now you give other links

can you try to be consistent? :)

I bet if you look at the HTML you will see it has multiple LD+JSON entries

[CRCinAU]

I believe its Coles changing the site - as the ones that fail all fail at different times... Probably trying to sell more stuff via AI 'optimisation' ;)

The problem you two are debating, I think is nothing at all to do with the links used. I think it's caused by things that are on special.
When a Coles product is NOT on special, the error does not occur. When a Coles product IS on special, the error occurs.

Which is why the link provided a week ago is no longer causing the issue.
@dgtlmoon this is one of my links that is erroring right now, and should be up until Weds: https://www.coles.com.au/product/simson's-pantry-premium-mini-pizza-bases-garlic-and-herb-6-pack-240g-6576438
