Most people don't realize that with Avionics (and many things aviation) and unlike furniture, jewelry, or even cars - there isn't much margin to start with. Anyone hoping to find a 25% discount or difference in price between different dealers is in for a huge awakening. The reality is that most avionics and electronics now start out with a gross margin to the dealers of high single or low double digit percent numbers at best. That is why you see some folks charging you extra to even use a CC, etc.. I've had/have people call me assuming there are huge margins to begin with and insist on a 30% discount. I have to tell them that when they find that let me know, and I'll start buying supplies from them!
There are folks that will sell somewhat cheaper than others, but you'll never find anyone that is 25 or 30% less than someone else, because it's just not there to begin with. That means that on an entire purchase of avionics you're looking at very small differences (percentage wise) and why we try to add value in other areas. The business model where the only value you add is being the low bidder isn't what we're all about.
As an aside, we do a fair bit of regular business re-wiring items / harnesses that folks already purchased once somewhere else...
Just my 2 cents as usual.
