I have 2 main products, each with different base shipping rates. When ordering 1 of each the shipping calculates as the sum of the two base rates. I would like it to use the highest base rate instead of the sum. Is that possible?
Example: A: Cost $18, Ship $6 B Cost $20, Ship $9
When ordering 1 of each the shipping total is $15, I would like it to be $9.
