TOPIC:

I want to buy this plugin but i need to know if it made a free shipping if is buyed 4 items from same product. I want to sell tyres and if a customer buy 4 same tyres he have free shipping. Thank you.

Dear Luciffere,
The devil lies in the details, as usual:
If a customer buyes a set of 4 idential tyres, do I understand you correctly that the whole order is shipped free of charge, even if the customer buys many other products in the same order?
What if a customer buys four different tyres? Does he get free shipping, or do you give free shipping only for sets of four identical tyres?

Best regards,
Reinhold

Free shipping only for four identical tyres. If the buyer buy another products in same order, the shipping remain free as long as the 4 identicaly items are in cart.

Dear Luciffere,
This scenario (free shipping if the customer buys a quantity of at least 4 units of a product from a certain category) was not possible in previous versions. We have now released a new version 5.7 of the plugin, where we added variables MaxQuantity (the quantity of the product with the most units ordered) and MinQuantity (the quantity of the product with the least units ordered), which you can now use. If you have only tyres in your shop, then the corresponding rule would be:
If you also sell other products and the 4-tyres minimum for free shipping should only apply to products from a certain category (tyres; I will assume a category ID of 42), then the rule would be:
Best regards,
Reinhold
