ECO (Extra Customization Options for Ubercart) provides additional ("extra") options to customize Ubercart.
Please see a list of features below. Some of the functionality provided also includes a degree of integration with other contributed modules like Legal, Webform, and Ubercart Discount Coupons. Among the customization options are using URL parameters to auto-apply coupons in checkout, requiring new customers to choose a password, and integration with the Webform module to pre-populate address fields in checkout.
Among other things you can accomplish with ECO is to have a shopping experience that does involve a product page or add to cart button. For example, you could include a webform in a block, via Panels, or through Views, etc. in which you collect information and pass it through to Checkout along with adding a product to the cart automatically. The Webform module saves the data entered regardless of whether or not checkout is completed in Ubercart.
Create just one block with the logged on user's picture, if he/she has one. In addition, User titles, points and badges are also displayed, if there are any.
