Google search result does not display my product price correctly - e-commerce

Question

I have problem with Google search result. I have product page and they do not display the price correctly.
I've tried to make them crawl the page again and again.
I have put the correct price in the JSON-LD.
<script type="application/ld+json">
[
{
"#context": "http://schema.org",
"#type": "Product",
"name": "Wishbone (Y) Chair - Oak - Natural Cord",

The expected price is £299. However it keeping saying that price is 119£ on the search result.

Answer 1

This looks like a canonical/duplicate issue. I looked at the cache for the example page:
/en/oak-natural-replica-wishbone-y-chair-hans-wegner
And it indicated it had been canonicalised to this page:
/en/black-replica-wishbone-y-chair-hans-wegner-natural-cord
Which has the 119 price.
Google is thinking that they are pages about the same thing, so merging them into one (canonicalising).
Product content duplication and canonicalisation is a well known issue, and not an easy one to resolve. There's lots of articles out there on it that may help.
You have a different URL for every variant of this chair. The only difference in content is one or two words mentioning colour or material. You may want to merge/consolidate them all into the one product/url making one strong and indexed page. Then mark up a price range.
