I don't know what your point is, but at AZO I have my car computer checked for free, borrow tools for free, and possibly drop off use oil for free. Just like the Jesse James commercial, seems most auto gurus I know like AZO too. The stores are seem clean to me too. Why wouldn't they be, no real work goes on there, they are stores.
They should not reduce the buybacks, they should increase them.
Buybacks are not to improve price but to improve anything per share, such as revenue per share or earnigs per share or p/e ratio. I do think if they continue the buybacks book value will go negative. However, I don't think that is a bad thing necessarily. if they stop the buybacks, I am out!
