I have, and they only want to sell me display with cable, and I find the price to the display to be overpriced.
"Sorry we developed the cables specifically for our own products, and we have a limited supply, so we have to keep them together for sales."
"The picture with heat shrink was prototype. We have them professionally made in factory"
I have advice them to remove the link you gave me to not make misundersandings for others.
They are only selling kit (display + cable), faire enough...
