Shopping cart / eCommerce WP plugin. Easy to setup online store. Powerful functionality. Include free e-commerce themes.
If you have a small setup/project and want quick integration of eCommerce in your WordPress setup you will find this plugin very helpful saving you a lot of custom code effort. I have purchased a theme from them and a few ad dons. There are a few glitches in the plugin but they still improving it with quick and stable iterations with new features for free. The support on top of all is phenomenal. So would highly recommend it if you have the same requirements.
I searched alot of ecommerce addons for WordPress and finaly settled with Ready! Ecommerce, one was the fact it is easy to use and the ability to import bulk products from a CSV and also have Sage Pay compatability.
I have to also say the support is second to none, I am outstanded how willing the plugin owners are to help get issues sorted.
Great Ecommerce plugin, outstanding support, easy 5 stars rating, I think it will only get better and better
