I like the shipping calculator better because if I were to ship an intake manifold to Ohio it would cost $15 and to Arizona it would cost $30. I like to pass the savings on to the customer if I can. But when you bend over backwards for people and they have to mention in your feedback that you made an extra $2.25 on them, it is frustrating. You would think that they would be happy to pay you the tiny amount extra. Heck, I tip my pizza guy more than that! Freakin' Cheap Skates!! And how do you like it when they say, "Before I leave you feedback, I want address the shipping charges". That's extortion.
