Wow, too bad. After a light cursory reading, I would personally not anticipate Walgreen's buying again any time soon. Just my opinion based on 45 years of consumer branded marketing and years of dealing with Walgreen's.
This was a bad plan or at least an ill conceived plan.
They are directly involved, they had to administer a payables dispute resolution. Others may want to gloss it over, or I may have missed something, but I believe this is toxic (again my opinion) you NEVER want to air your dirty laundry.
They know that money was a problem and the vendor sold them goods they did not or could not pay for.
This is not pretty. But again, maybe I may have missed something. Im going to a ball game folks.
Good luck.
