I am opposed to Walmarts company mantra, but it'd be too hypocritical of me to say that since it has the largest selection of everything in my area (minus home building / car supplies). But, $12 for 5 quarts of 10W-30 or 20W-50 (bike) keeps me coming back. Prestone Antifreeze is $11/gal here. Bosch wipers are typically a couple dollars less, each, as well.
It's on the way home from work, the closest to the house, has a fresh produce (non-organic though), and a quite sizable grocery aisles. I wish I could turn away, but can't.
About your LED's: those lights aren't any better than the ones available in Autozone's play aisle for newly-mobile teens. BrightLEDs.com and eBay lights from China (I'm guilty) are brighter and just as easy to install. I used my LED strips to illuminate my engine bay over the stock bulb, my tonneau cover, and it turned my cabin into the surface of the sun so I can find that damn pen/quarter/phone that falls beneath my seat.
I don't use MotorCraft...
Ugh, why don't you buy Motorcraft? Especially from Walmart? Please tell me you buy Fram because you like the orange color and the cool textured grip on the end.
