WooCommerce Pres-sales, Time offers & Expiring System (WCPS) is a powerful tool that adds to WooCommerce many new features to plan Pre-sales or Time limited offers for all products
The idea behind the plugin is to have a tool by which the shop admin can configure special price for items according to a selected period (NOTE: in case of variable items, the plugin allows you to assign presale/time limited offers to the items, not to its specific variations). This period could be a pre-sale period in which offer a few amounts of items to a special price or a special offer for a weekend or seasonal offer.
With WCPS plugin you can do all of that. Furthermore you can also limit the offer period not only by date, but also using a “Goal threshold” value and only to a specific set of user roles
