Wanting to give your customers a free gift with their purchase in WooCommerce?
Then watch this video because it will show you exactly how to do so in Advanced Coupons:
On your coupon edit screen goto the Add Products tab.
On this screen, you can do a product search for the product you want to give away with this coupon.
Set the quantity and hit Add.
Once you save, this is now active and whenever this coupon is applied, it will add this product to the cart and zero out the cost for that line item in the user’s cart.
The other place you might want to check is the Cart Conditions where you can define all the things that need to be true in order to apply this coupon.
This means you can restrict it so the coupon can only be applied when a certain other product is in the cart for example. Here’s a great guide on how to give away free products with purchase in WooCommerce that might help.
