Was working on my never ending project yesterday, test fitting front sheet metal, making battery cables, running trans cooler lines etc.... I bought pre-cut sections of 3/8th inch hardline from O'Reilly's for the trans cooler lines. The stuff that is pre-flared with the fittings already on it, I wanted to do two separate pieces for each line with a union in the middle. Ease of bending and fitting and service-ability were deciding factors. When I went up to pay, with my "shop discount", the unions rang up at $4.99 each. I nearly choked!! The guy at the counter said I think we have these in back. Two minutes later he reappears with the EXACT SAME FITTINGS at $1.99 each! Only difference is the packaging! Moral of the story is the fittings on the floor, packaged in the large, anti-shoplifting box are severely over-priced and it never hurts to ask if they have anything in back!
