show price before group discount and discount percentage

[teralite]

Hi guys!

 

I hope someone can help me with this problem.

 

We have, in the database directly changed our prices with *1,7

 

Now, we want to show that price in the product page, see picture.

I want this price to be static, and never change regardless.

 

Also, i want to show the discount percentage that each group get, for example we have one group that has 50% discount.

The problem here aswell is that its not 50% all over, but some categories have other discount percent, for example 40% on led tubes.

 

Anyone got any idea how to make this work?
