I intially hadn't thought of Amazon either, but now I have a habit of whatever I am going to buy (from any store), googling the part number and seeing if it is cheaper somewhere that is still accessible. Just takes a second and saves a bunch of coin. I saved about $700 on the tool boxes I just bought. Same brand and model, just different store.
As for shipping, I didn't have to consider that since I have Amazon Prime, its free shipping.
I know that washing and waxing my car with the present condtion of my paint is like polishing a turd.....but it's my turd and I want it polished!
