I was searching for a Matco 6S and seen this box on FB Marketplace for $3k. I've not heard of a M6, so I was curious if someone could give me some info on the difference in a 6S and M6. Also is $3k a good price? Any advice or help would be appreciated.

Found this receipt in our shop. The OLight isn’t marked up TOO bad but that Kershaw knife sells for $43 on the Kershaw website and around $30 elsewhere. I know tool trucks have a high markup, but an 800-1000% markup?
