My description windows specify shipping charges of $2.00 for domestic and $5.00 for international shipping. The charges are specified 4 times in each description. I want to change my shipping fees to $3 and $8. I know how to make the mass changes in the Item Description box using the advanced edit function but am not seeing how to make the mass/batch changes in the Mobile description box. How do I go about making mass changes to Mobile Item Description box?
