Invalid floating point number in property 'price' (in 'offers')

Topic summary

Main issue: Google Search Console reports “Invalid floating point number in property ‘price’ (in ‘offers’)” on product markup. A code snippet shows the price rendered as “£4.18” inside itemprop=“price”, which suggests a price-value formatting issue.

Impact: The reporter says affected items are marked invalid and cannot be indexed.

Evidence/inputs: A central code snippet was provided showing how the price is output in the HTML. A helper shared a guide specifically about fixing this error in Shopify and offered direct assistance (email/LinkedIn).

Constraints: The site uses a custom theme, and the reporter does not have coding background or know where to place code changes.

Next steps proposed: The helper asked which theme is used, learned it is custom, and requested store access via a link to send an access request and investigate.

Status: Unresolved/ongoing. Pending the store link/access so the helper can review the theme and apply the guidance from the referenced document.
