I'm guessing a few reasons: 1. The kit has like thirty individual devices in it, many of which are unique or have a bunch of tactile buttons and sliders. Marketing for the product suggests that they were designed to be really durable so students wouldn't be afraid of breaking them. 2. Because it's a relatively niche accessibility product, they probably don't sell very many of them. So they need to charge more to cover all the fixed costs of designing the product, setting up manufacturing, writing all the companion materials, etc. 3. In the US, the APH Federal Quota Program subsidizes some of the cost of buying products like this. https://www.aph.org/about-federal-quota/ https://www.aph.org/about-federal-quota/ also suggests that there are programs where you can borrow or rent the kit instead of buying it.
