I have a Magento site with around 900 products and need to add related products to each. Related products are based on style and size. As example please see this product which I have already done: shatterboxwebdesign [dot] com/roche/purse-styles/handbags-42/aztec/sazwipwlbbbt [dot] html
This purse is a small aztec, so under related products it shows all other small aztec purses. All small aztec purses will have the same related products. This is the same for medium aztec purses, small burma, etc.
If you have any questions about the project please let me know.
