This button (module/plugin set) will allow store owners to apply a special price for single products or categories. Coming in September, this module/plugin set will also permit the display of the button during specific times:

1. Based on calendar days or ranges
2. On specific days of the week
3. During pre-defined periods of sustained inactivity
4. Apply to one or more categories or subcategories
5. Apply to slow selling products, high selling products or all products
6. Includes alert emails to customers who request special offer email alerts

This module/plugin set really lets all store owners using AJAX eShop, take more control over your store's prices, via intelligent software, and benefit from higher sales as a result.
