Unfortunately, the price for the e-ink display is "€2,300".
Nevertheless, there has been a recent decrease in price of this SDK hardware. I believe it’s been driven by eInk having created a modular substrate (all the stuff in a display, minus the panel) allowing cheaper iteration on their panel technology. So people can buy the SDK substrate component once; and then buy a new SDK panel component each time eInk reformulates it. Lower manufacturing costs + cheaper logistics for eInk Corp. = cheaper costs for everyone else, even when buying the whole kit together.
(Sort of the same reason that essentially the same cube-shelf design is cheaper from IKEA — IKEA just packs wood tightly into a flat box, and then piles those flat boxes up in a shipping container; and when you buy it and get it delivered, it’s still flat right up until it’s in your house. Other manufacturers, meanwhile, assemble the thing at some point — whether at the factory or at the story — and then ship it at least once in assembled form, where it’s taking up a huge amount of space in the container / on the truck.)
If they would let me, I would actually be perfectly happy to go to the IKEA, pick the boxes myself, and even load them into their truck myself, if that would result in the items then being driven to my house. I have to imagine that IKEA would be pretty okay with that arrangement as well. I wonder why they don’t offer that “service”...
Although I thought they'd deliver almost everything by now too if you want. but haven't checked in a long time.
SO basically you have two options: either use their online story (the most convenient option) or use public transport to go there and a taxi (of adequate size) to get back home. I usually use the former option after having visited the store first to actually try the products I intend to buy. I don't treat their stores as stores but as showrooms.
