I need a plugin built for CubeCart version 5.x that limits customers from purchasing more than a certain quality of a particular item.
The plugin should add a field to the products data under the general tab which says limit. So if I was to enter 5 as the limit for a particular product it would only allow 5 purchases of that product per email address. If the a user tried to purchase 6 or tries to purchase 5 a second time if should show a warning on the checkout.
There should also be a global limit in the plugin setting to limit users to only buying X of every item in the store.
This needs to be built as a plugin and more information on plugins can be found here [url removed, login to view]
