I'm so sorry. That's funny my Home depot has cut pressure treated lumber for me before. I have had the same problem hauling it. Are you sure you don't have an alternator problem? They will test it for you at auto zone.I had the worst day today. I needed lumber for a remodeling project. But my truck battery died.
Can't fit 10ft lengths in a car. Home Depot would not cut my boards to length. (Because I needed Pressure treated planks) They don't cut those.
I'm not sure if AutoZone will make good on my battery warranty tomorrow, I hope they do, but It's Battery #2Totally wasted day!
