The secret is.... well it's a secret!
There used to be a Rutland local to me that I used to buy from. They got bought out by MSC & moved the location a few blocks over & turned into a MSC location. The same salesguy that I dealt with at Rutland works at that MSC. I'm cool with him, been buying from him for years, & he always tries to give me the best possible deal for high dollar items.
For example, I bought a Bison 6.25" 3-jaw Set-Tru. List price is $1032. I normally bought chucks from Ajax as they have great pricing. This chuck is $740 at Ajax. MSC's "normal" price is $1106. My logged in price at MSC is $797. My sales guy gave it to me $550. I have to pay tax but still way cheaper than anywhere else & I don't have to pay shipping for anything I buy from MSC, even if they have to transfer it from NV. I love MSC.
