Article Limit Per Order

This module extends the article structure with the maximum order amount of a single article. This amount can not be exceeded per order.

About the module

Hamster buying is not only a problem in retail stores. Many shops have the problem that people buying articles in a huge amount, especially in days of sale. To avoid that, this module adds the functionality to add a limit of maximum amounts per order process.
