This is only true in the sense that there is a cost to move goods, but it is not true in the sense that retailers charge more to move the good to you. If it were, I wouldn't be able to reliably purchase goods shipped to my door for equal or less than what I pay in physical stores. When shipping is included in the price, that means that the shipper bears the cost of shipping by taking a smaller margin. If I were to bear the cost, it would appear as an explicit cost or higher prices, neither of which are happening.

Higher cost than what?

By the same argument, customers are paying the costs for Best Buy's internal logistics and retail floor operations to enable “free browse and instant pickup”. If those costs are higher than Amazon/NewEgg's costs for "free shipping", I'd expect to see exactly the relative prices that you're seeing.

I'm sorry, but I can't track the point you are trying to make.

I'll reiterate my point that shipping is a cost that has to be paid, but who bears that cost is not necessarily the customer. If it was the case that the customer was the one bearing that cost, there would be a difference in the price you pay for goods at a physical store vs. goods shipped to your home, implicitly or explicitly. There is generally no difference, and in many cases, ship to home is cheaper because you can select from more retailers.

I think you're confusing who writes the check vs who bears the cost. The person writing the check isn't always the one bearing the cost.
