I seriously doubt that you, your partner or your business has a tax ID and even if you did it has nothing to do with getting a discount. It only means that you don't have to pay sales tax when you purchase a product at the beginning. I also seriously doubt you guys are placing $1000 orders either, especially with the discounting structure Detailed Image REALLY gives you guys. 10-15% is nonsense. I know that the more work you spam, the greater the discount. Stop skirting around the truth to make DI look like the good guy here. They're obviously not!
It's a shame that with all the work DJ Mayonase claimed to do in his 10,000 square foot shop and touring all across the county detailing cars that he'd need to stoop to such low levels for big brother to give him a reach around. More BS I'm sure.
