specials per size

[lizaa]

Hello,

 

I've rugs shop, each rug has more than one size and each size has its own price, each price is inserted through products attributes in admin.

 

my problem is i want to make special price for each size, I don't know how to do that, i searched for any addons which can do that but i failed.

 

Does any one know how can i do that?

 

Thanks.
