The reward is capturing the sale -- and to do so, a merchant has to be flexible in their offerings. That BestBuy signed an exclusive (or exclusionary) contract that binds them to Walmart's will says more about the shortsightedness of BestBuy management than the maturity of any one technology. I don't think I'll invest in BestBuy stock -- the company that makes such decisions doesn't have much of a future.
