Addons are extra modules developed by osCommerce community members to add more features to osCommerce shop. OsCommerce Addons are very good modules to enhance your shop and also they are free. But they are risky because there are many bugs and have not proper support.
1.Product Attribute Filter for osCommerce
Attribute Filter is a box, which has a set of Attributes and their values with checkboxes. Please note, this script shows only that attributes, which is added to products from current category. For example, if you are currently in category “Graphics Cards”, you`ll see attributes for graphic cards, like Model and Memory. But if you are in “DVD Movies” or other category, their products has not attributes like Memory, so, this attribute will now be shown in this category. This is very useful, because you dont need to see attributes from other categories, just only that you need in current page.
2.osCommerce 2.3.1 Dynamic Meta Tag Module
One of the weakest areas of osCommerce is search engine optimization. A default osCommerce installation generates nothing more than a page title, and then appends the store name to that! The store name is not something potential users will search for when shopping. And to make matters worse, the osCommerce URL structure can very well cause a shop to receive duplicate content errors.
