Hi
Keep in mind that the margins in the test equipment distribution business are pretty slim. The way these guys make money is by moving inventory a lot of times a week / month / year rather than high markups and little action. The offshoot of that is the basic fact that a discount code rarely works on an "on sale" item. In fact, finding a blowout sale on this or that likely gives you more off (on Cyber Monday) than any discount code you might find.
