My Autozone has the same blades that my Wal mart has, only diff. is $2.00. I'm not buying "BMW parts", I'm just changing wiper blades? I also buy Zymol wax for $3.00 less then my autozone. Is anti-freeze a "BMW part" also? By the way, I hate wal mart but I won't spend more at autozone for the same basic maint. items like fuel injector cleaners, window cleaners, ect... Like I said, I hate wal fart because I was a purchase agent for them for six years and I can tell you that the difference in Trico,Anco,rain-x, ect. compared to wal fart, is price. Wal Mart buys billions of these at a set batch rate,(just like a group buy). And since wal fart can buy more than autozone they get a much better price. Ever see the " American Eagle" tire at wal mart? They had a deal set up with Goodyear to produce these tires at a discount that was only available to wal mart only at a one time deal. The tread pattern and compound turned out to be great, (I have them on my Volvo S80 right now.) Same product diff name. My point is that wal fart gets many of the things they sell from the same vendor as the small guy's, but they pay less. GE and Sylvania lights are like the wiper blades and other products they sell, same quality. A six dollar bulb is purchased for roughly 90 cent's in a batch buy! As for product quality you are right in a way, Wal Fart buy's TV's, Stereos, Treadmills and products like these from the manufacture built with inferior parts that barely pass quality control standards. They make a deal with Wal Mart to move these items instead of taking the loss. If the item fails they will gladly take care of it, because the ratio of failure is low, despite having low quality parts. Every time they open a store, ten family owned stores go under, that is the main reason I hate Wal Mart. But I like my $ and I never use low quality item's on my car!
