nattyp on "[Plugin: WooCommerce - excelling eCommerce] Adding RRP in front of Price"

Hi,
Was hoping someone knew how to add a rrp (recommended retail price) in front of the pricing of products on the shop page? Tried to find the corresponding template to modify but had no luck.
Any help will be greatly appreciated.
Cheers
