The 150 miles is a round trip and ND interstate speed limit is 75 so I make the trip in about 2.5 hours. I buy a few things online but it's just nice to get out of town now and then. I only put about 11,000 miles a year on my car; most of that is a couple of relatively long trips in the summer.Wow! What a drive. At 55 mph, that would be almost 3 hours of driving. And then, there's the gas, not to mention wear & tear on the vehicle.
If it was me, I'd lean towards buying online and foregoing Arby's.
