Combined Orders over 15 oz is incorrectly showing/using Standard Shipping option: USPS First Class Shipping with outrageous fees.
USPS First Class shipping only allowed up to 15 oz. So, this issue should be corrected to not show/use the Standard Shipping option for USPS First Class on combined orders over 15 oz and only show/use the Expedited Shipping option.
I lose many orders because of this issue. Please correct ASAP!
