Google Checkout - Shopping Cart Software for ECommerce Storefronts

PDG Software has recently completed our integration of the Google Checkout payment processing
engine into our ecommerce shopping cart applications.
Google Checkout is the key for merchants to sell online and manage their Web store orders.
Google Checkout provides a simple and checkout process for purchasing customers. Registered
users can select the Google Checkout option within the PDG enabled store, log in to their account
within Google's secure site, and complete their purchase without having to fill in any information!
New users can easily register for a Google Checkout account, which can be used at stores across the
web. Orders and shipments can be tracked for all purchases within a simple web based interface.
To begin accepting Google Checkout payments within your PDG enabled Web store,
sign up for a Google Checkout seller's account
now.
