WooCommerce – a Google Checkout Alternative

If you have a WordPress site where you sell physical goods and you have used Google Checkout as your online processing center, you will need to replace that method this November.
A great alternative is WooCommerce, which is a free plugin that allows users to customize their selling and shipping options for an additional fee.

WooCommerce is a powerful, extendable eCommerce plugin that helps you sell anything. Beautifully :)
