We are using ASPDNSF MultiStore 9.3 and have integrated AvaTax and are using real-time shipping. On checkout1.aspx, the tax amount from AvaTax is correct. But after the shipping method is chosen (no matter which one) and the user moves to checkoutreview.aspx, the tax has been recalculated using subtotal + shipping.
Has anyone else seen this behavior?
Thanks,
Ray
