I think it really depends on the volume you do.
It's easy to have good relationships with wholesalers and their sales staff when you are always buying a ton of material.
For a smaller shop I don't think you get the same level of treatment.
I get the same service, but I don't get the same prices at a supply house as larger shops do.
Wait....shop? I'm a far cry from a shop. Don't want to be a shop, either. I'm just a guy who works.
About 8 years ago I downsized my vehicle from full size van to mini van. Then I downsized again to a small pickup. Last year I downsized again to a Ford Focus wagon. Think...Geek Squad.
It was an intentional downsizing. My work started to shift to more bid work, small stuff like kitchen remodels and basement finishes. I realized that service work was interferring with my deadlines, and had to force myself into a situation where I was not equipoed to do service calls.
I simply don't have the room to haul stock. But I've got plenty of room for my tools, and even a 6' ladder on top when i need it. And the small amount of materials it takes to do each job.
Yeah, I get laughed at by blue bloods when I roll up on a supply house and ask for 1 roll of 12-2 and 3 single gang boxes....but I don't care about that. Counter salesmen still treat me with utmost respect
But the pricing. And the time it takes to go get it.
But sometimes it's not about time, it's about availability. A week ago I added a 30amp plug for a rolling hot cart in a deli. I needed a bolt-in breaker, so I just decided to get everything from the supply house.
2-pole 30a GE bolt-in breaker was $67.00
100ct. 8" zip ties was $27.00
I don't have a frame of reference for the price of that breaker, but I know for sure that I can get 100 zip ties at Home Depot for around $10.00
$17.00 to save a second trip. That's a bargain. But if I hadn't needed that breaker, HD would have had my business
