Updating prices automatically

Hello,

I'm trying to find a solution for automatic price updating from my supplier's web page.

To get the price now I have to login to the web site, find the product, find the price, manually reduce it, add margin and put it to my opencart shop.

Example: regular price is 100,00 at my supplier, then I have 4% discount there, so my price is 96,00. Then I add my margin - let's say 10%, so I will sell the product for 105,60. Now I have to enter the price to OC manually.

I was trying to find an extension but didn't find any. Does anybody know for an extension to parse the prices from a web site and automatically change them in OC ?

Thx
