Hi, I'm a beginner and I'm using version 1.8 and I need to compare shopping cart prices across different stores.
My question is With these attributes -> price, priceofstore2, priceofstore3
can magento show on the shopping cart -> price, priceofstore2, priceofstore3 and their totals?
Right now, Magento doesn't provide any functionality to achieve your requirements. You need to customize the Magento for that.
