I would like to know if, after some conditions are met in a customers cart, it is possible for me to create a 'temporary' shopping cart price rule for that specific cart instance only?
For example- a customer uses a discount code in the cart, but I want to give this specific cart instance another 10% off. However, I don't want to create a "global" shopping cart price rule that will apply to other customers who are checking out around the same time.
Is this feasible? If the nature of shopping cart rules is that they exist irrespective of a shopping cart instance, then is it possible to modify the cart total/shipping/etc manually?
Thank you for your suggestions!
