I have two shipping profiles: 1 General Shipping for sale-priced items and 1 Free Shipping for normal-priced items. If a person places one item in the cart that is on sale, they see normal shipping rate options (UPS Standard Shipping, 2nd Day, and Next Day). If a person places one item in the cart that is normal-priced, they see free shipping. But if they place one sale item and one regular-priced item in the cart, they only see the option for Next Day Shipping. No other shipping options are available. How do I fix this so that the customer can choose from all of the available shipping options, such as Standard Shipping? Thank you!
