hello,

This code is working except for one small hitch. The item adds once the cart total is met and deletes if the cart total is changed, but there is no way to manually remove the item. When I try to delete the free item from the cart, the page just refreshes and the item is still there. Any ideas?

Seeing the same. Item is removed, but immediately added again because it wasn't found. When you remove other items from the cart until $cart_total is reached, you can delete it. Curious about a solution too.

It doesn't delete product from cart if total goes below minimum.

Based on my testing it doesn't delete product from cart if total goes below minimum but i think they didn't include everything. Its sample code to get you started and not a finished product for immediate usage.

And you have an idea how to modify the code to add the product at a specific price. I want it to be free for 0.01.
