First off, we understand and respect corporate philosophies.
We also know from experience that some companies - small or large - are purchasing displays others don't.
Experience is also that the ones who have a display will sell product and generate revenues the others don't.
Key word is Display, our "samples" are incomparable to other material like tile, marble, etc., they are full blown functional displays with lighting, power adapters, controllers, etc. etc., production cost of which are much higher than a tile or piece of stone.
Here's a thought for companies insisting on their philosophy:
So you have a 20/ 50/100k job and with our product potentially can save half or more but will not spend a minimal amount for a sample/ display. Penny wise and pound foolish springs to mind.
