Is it possible to change the product price?

Hello Weavers…

I am helping one of my friend in building a e-commerce website where he would like to edit the price of the products via web (i.e CMS) . Any thoughts if RapidCart Pro or Payloom 3 has this ability? Or if it can be achieved by integrating these plugins with some CMS options like easy CMS / Armadillo stacks?

I think changing the price tags should be made editable (for the site owner) by these plugins outside RW. Otherwise only the people with Mac/RW would be able to use these plugins for selling their products online.
