Why won't they? The other day I needed a set of air hose tools and looked it up at Amazon, saw it for $19. Went to my local store auto parts store because I wanted to support my local business and they have a fraction of the Amazon set for $42. I ordered it from Amazon and had it in 12 hours. Needed lawn mower filters, at home depot, it was $10.99 for 1 filter. For the 2 types I wanted, got them for $8.99 for 4 and 5 pieces. Using amazon is not even fair. I won't buy food, expensive electronics, or really bulky items from them, but for most things they are seriously crushing the competitors.
