Hi,

I'm having a problem in listing_price modification , I want to add a word before the price itself , here is an example : " Preço: R$ 550.00 por conjunto ," but the maximum I could "R$ 550.00 por conjunto " then what sentence modify or add to achieve the desired result?

I sent next to that post one print of exactly what I want to modify, is selected.

Thanks in advance.
