The basic approach I see a lot is just removing the price HTML from the theme. That sounds like it will work okay but there are a few other places that your prices could "leak" if you’re trying to thoroughly hide them from customers.
First, some themes add tags or other types of invisible data to the page like Facebook OpenGraph tags which are used when people share the page. It’s common to see the price of a product in here (e.g. og:price:amount).
Removing these are easy, they a just a quick edit to your theme.
From what I can tell, you can’t remove this at all.
Finally there are also two hidden urls in Shopify for products in addition to the main product page. To find them,
This is the JSON view of your product. In there are your variants and prices again, along with a bunch of other data.
(JSON is programmer-speak for a specific data format. It’s similar to JSON-LD from my app but used differently.)
For example, simakara monocular review
You’ll also notice that all variants are shown with their prices so if you’re hiding variants on the main storefront page, they still might be showing up here.
These are built into Shopify and I’m not sure if there’s any way to turn them off or disable them. I also know some apps use them behind the scenes too so even if you could turn them off, it could break something else.
If you want to completely hide prices in Shopify you need to make a decision about how much work you want to do.
Shopify’s wholesale channel seems like it’s a version of #3 but it’s for Shopify Plus only at this time.
Completely hiding prices is sadly, nearly impossible in Shopify.
Once great optimization is to make sure your product’s structured data is setup correctly for Google’s Rich Snippets. With those you’ll get more traffic and better converting traffic.
You can either audit your store’s structured data by hand or install JSON-LD for SEO and have all the structured data you need.
It’s already helping over two thousand Shopify stores with their structured data and it could help you too.
This is an example from your store:
I'll add a .json in a link below pointing to one of your products. This info about products is always accessible.
@Roger_McEffort, from a development standpoint, it limits pings to the server by having all that data upfront and leaving theme developers room on how to present it.
Private data thankfully is hidden away. I'd contact support about this. Maybe they know how to filter data which gets served out. (Might break features using that data afterwards but can't hurt to ask.)
