schoolboy - it happen from time to time, but customer will know what to expect. He can choose and decide.
At the "practical" level this is not so much an issue...
I am referring rather to HOW zencart will calculate appropriate shipping.
You see... if you make shipping options PRODUCT SPECIFIC, zencart will apply whatever cost is applicable to that PRODUCT.
So.. it may be that the customer is agreeable to having 3-5 day delivery - even if a couple of products are 24-hour delivery, but ZC will have calculated the 24-hour delivery cost and applied it to the total amount due - simply because it has been PROGRAMMED to do this.
What happens then, is the customer is CHARGED for 24-hour delivery on those PRODUCTS to which that shipping fee has been programmed, even if the customer is OK with 3-5 day delivery.
Zencart has no way of knowing how the customer "feels" about having everything delivered at a slower pace... it just knows that when it sees a product that requires the 24-hour charge, it will dutifully apply the charge, and add it to the total.
