Amazon's $1 billion acquisition of mail-order pharmacy startup PillPack created an industry-wide frenzy, as prognosticators forecast doom for traditional pharmacies like Walgreens and Rite Aid. But Amazon still has a long way to go if it wants to drastically change the drug supply chain.

The big picture: Amazon is buying a small player in a highly regulated industry dominated by powerful incumbent companies that aren't willing to give up their turf. The online retailing giant will have to build or acquire more parts to make a big difference.
