My formula,,, buy everything I can in the US, Never use the UPS RIPOFF,,,save thousands every year, which pays for other things like vacations, and hunting-fishing trips. Never buy Leupold, and some others. Even a set of shocks for a few hundred dollars, saved me about 35% plus, and I didn't even have to burn my gas to go pick them up,,,,, 4 days to my door. Do some math folks. If you make $40.00 per hour you would take home about $25.00. You would need to work over 3 hours just to pay the difference I saved non my shocks, let alone everything else you buy. It took me less than 30 Minutes on line to find good shocks for my Duramax, then another 10 minutes to order them. I would have spent more time than that just to go pay more at a store here, and that doesn't include my Fuel. Your mileage may vary.
