Hey @Advertfox Just confirm and tell me whether you followed these exact steps to set your product’s price or not

first open the product dashboard in you Shopify in your right hand side you can see the add products button click on it and when you done your product upload scroll down and you can see the variants option just like this

after that in your right hand side you can see the columns option click on it and find the compare price option and then set that price that you want

that’s it follow these step and then your problem is solved

I guess I’ve already wrote it, but anyway:

You need to configure your Product options app properly because theme code shows proper price, but app overwrites it with wrong amount.

Or contact app developer for fixes if you believe that it’s configured properly.

Hi, sorry which product options app are you talking about ?

Do you have several?

This one – EasyFlow Product Options - Add unlimited product options & variants with easy customizer | Shopify App Store

Hello @Advertfox

This is because it’s a correct variant price set in the admin, but the theme is not refreshing the displayed price when selecting the size. A lot of themes also require you to attach the variant selector to dynamic price updates. Are the 3XL and 4XL really separate variants with different prices, and does the price change with color? If not, then it’s likely theme logic or legacy product form code. An easy solution is to either update the theme version, or use the Dawn style variant scripts. And make sure no app is overriding the product options.

Hey @Advertfox ,

I hope everything is good.

I think I’ve found the culprit in the code.

To reach the file:

  1. Open Shopify Admin

  2. Go to Online Store → Themes

  3. Click Actions → Edit Code on your current theme

  4. Navigate to Assets folder and find common.js

In common.js, locate the priceObserver - it should look something like this:

Now comment out the calculateTotalwith its if condition call like this:

image1729×568 38.7 KB

This will ensure that the price doesn’t get updated recursively/duplicate times. The calculateTotal function is already being called elsewhere (in input handlers, etc.), so this observer was causing unnecessary and conflicting price recalculations.

This solved the issue for me. Hope it helps!

Suggestion:
I suggest to test this in a staging/draft theme.

Important note:
Although this change resolves the immediate issue, I strongly recommend thoroughly testing all price-related functionality after making this change - including product option selections, variant changes, quantity updates, and cart additions. Please verify that everything works as expected in your specific setup before deploying to production/Live.

It’s all good, but that file is not part of the theme, it belongs to the EasyFlow Product Options app as I mentioned previously.

Other than that - your diagnosis is right.

Thanks @tim_tairli ,

@Advertfox , the best way to fix would be the app team, you can share the above screenshots for apps’s reference.
