Show full price then sale price of an item

Hi Nicolas thank you again for getting back to me you guys are great. I am still unsure how to do it. This is what i am trying to achieve
I need the main categories that i have already created on my shoponline page www.joujouandlucy.co.uk/shoponline/ . Baby, Girl, Boy, Accessories (and the sub categories off those main categories that have already been created) to appear on my Sale page without having to create them again. Please can you tell me in more detail how i do it again
Thank you
