I am currently working on wine-express.pl, an online wine shop.
What I need to do is set up free delivery when one adds a certain bottle - so when one adds an item with set free delivery no matter what is added more there is free delivery for the whole cart.
Example: There is an item with free delivery "A". You add this item to cart. Normally you would pay 35zł for delivery, but since you're buying this product you don't have to anymore. However, you also add another, normal item "B". Supposedly only for one item there is free delivery but I need to make it a higher priority or something like that. So after adding B you still don't need to pay that delivery fee.
Any ideas on how to solve this?
