adding a text after the price (on the front end of the shop)

[LucasV]

Hi!

I would like to add some text behind my prices on my prestashop.
I think I need to change this in the product.tpl and catalog tpl but not sure what to edit or add.

Example:

original: "€120"
edited : "€120 /day"

I need this on the prices on my homepage, catalog, and product page.
Hope someone can help  

Thanks for your time.
