TTI's where is best place to buy??

A few years back when they were selling, I was buying performance Mopar parts from Koller Dodge, good deals and nice people. Well, I was asking about TTI hedders because Koller would pay for the shipping. Koller told me that TTI was was upset with him, because they didn't want freeshipping. He asked me, now does that make sense, why should they care?
