Trying to add text after price to some collections

Is there any way to add text after the price to some collections for example, I want to add ‘Per SQ/M’ to some collections only

can you share more context about your code, please?

Hi,

So Im trying to add text after the price on some product collections. For example it shows a price of £28.00 and I want it to look like: £28.00 Per SQ/M.

Im using the optimal theme from Adorn Themes

Does that make sense?
