group buying in WooCommerce

Good Evening, I’m trying to get something similar to a pre-order, but the item will be available for shipping only if a certain number of users buy the item or its variations (same item but different size, color, etc).

If the goal (minimum number of orders from the same user or from multiple users) is not reached within a certain time-limit all the existing orders will be deleted.

How can I implement collective buying (group buying) in WooCommerce? you have something?

best regards

need that too… any idea?

Also interested.

Interested as well! I found this plugin that might do the trick: http://www.codelicense.com/item/woocommerce-group-daily-deals/9910045
