11 Cool & Surprising Add-On Modules for Ubercart

Just when you think you know all that Ubercart can do - what more is there besides payment, stock, tax and shipping modules, right? Surprise! Ubercart has some interesting Drupal 6.x modules mixed in the cart - if you know where to look.

1. Signup Integration allows users to purchase signups for themselves and/or other people for events where nodes are configured as Ubercart products. http://drupal.org/project/uc_signup
2. Organic Group Subscribe makes it possible to sell Organic Group membership to one or more groups when a user purchases a particular product. http://drupal.org/project/uc_og_subscribe
3. Donation Products allows the creation of donation products that are not shippable where end users can specify a donation amount before adding the product to the cart.  http://drupal.org/project/uc_donation
4. Donation Incentives can be thought of as rebates on the purchase price of products, where the rebate is a donation to charity made in the consumer’s name. http://drupal.org/project/uc_donation_incentives 
5. Invite Discount grants a discount coupon to an “inviter” each time an invitee make a purchase. http://drupal.org/project/uc_invite_discount
6. Variable Price allows customers to specify their own price for a product instead of using a fixed price. This makes it a useful module for donation sites! http://drupal.org/project/uc_varprice
7. Who Bought What keeps a list, per item, of who bought what! This is important if you are selling tickets to an event, or keeping a will-call list for a performance. http://drupal.org/project/uc_who_bought_what 
8. Upsell is an advertising module that allows merchants to associate multiple “related” products together with the hopes of increasing a customer’s purchase. http://drupal.org/project/uc_upsell
9. Marketplace allows Sellers the ability to view their products, track their orders, and monitor their sales, while Store Administrators can view seller reports. http://drupal.org/project/ubercart_marketplace
10. Restrictions will do its best to prevent the wrong sort of people from ordering the wrong sort of goods, or to ship them to the wrong kinds of places. The module was originally developed for a site that sells wine. http://drupal.org/project/uc_restrictions
11. Ticket is a ticketing/customer support system configured to collect emails from various email addresses, and create tickets from the content of the email. This module integrates with Ubercart Orders and Contact modules, and includes a template feature perfect for creating customer support responses.  http://drupal.org/project/uc_ticket
