Ubercart Restrict Qty lets you add a very basic Restrict Qty. to a product in your Ubercart store to limit the quantity of that product in the shopping cart to 1. This is useful for single purchase products or for instances where it just doesn't make sense for a customer to purchase more than one and you want to prevent it from happening.
Public Bookings allows registered and unregistered users to book predefined resources. These booking requests can then be approved, rejected, or modified by an admin, with notifications to the user.
Available and unavailable dates and times can be specified for each resource.
Requires the Bookings API module, the Date API (and its submodule Date Repeat API) and Views. Use the corresponding Bookings API release! Never ever mix DEV and STABLE between those two modules (e.g. dev from API, alpha from Public or vice vesa).
