OK I think I will go ahead and keep it like it is using the checkout form on my site. If I was to delete the checkout form, does the realtime UPS shipping and tax get included on paypal checkout form?
If not deleting the checkout form I have another problem...when you enter an order and fill the checkout form but dont submit the order and you go back the shipping and tax are showing in the cart, so when you add another couple of items to the cart, the shipping stays the same. Why would the shipping be shown in the cart when going back to the cart if it did not show in the cart from the beginning.
Also the UPS charges are way to much. Im using Ground for 3 lbs. it charges 37.00 for shipping. When I do a quote at UPS it is only 9.00. In the ecart object I set the weight to oz, and UPS uses LBS.
