I want to do this without using Store Manager for Magento .
I have a movie store there are formats for the movies like DVD, Blu-Rays, and UMD i want to set prices for the formats, formats will be multiple for the same products with different prices for the individuals products and there for i have added attributes as format name and that should contains of prices and i want that in detail page if i can select a DVD format it should swatch the main price with DVD format price . i want to repeat that with every formats so the price should get shown up everywhere like in shopping cart in checkout and in admin sales order tab.
I have tried to edit price.phtml of the product/catalog and i am getting price by formats there also but i have no idea hoe to swap format price with main price, please give me at least some hints so i can complete the functionality, I am so much worried about this,
I am expecting reply from Moshe
