For individual parts, my guess is they won’t sell parts other than ‘packs’. But we can organize a ‘wall of parts’ on this forum, if the moderator agrees, where we could define the price for new individual parts.
For example, if the ‘mechanical’ kit is 99$, and if you buy it to replace the rear left leg only, then you can make an offer in this forum to sell the remaining legs for 20$ each, the body for 30$, the same would apply if you buy the motor kit for 99$, a single clockwise motor and its wires could be defined 25$...
Let’s wait for the first kit deliveries and see if any of you are interested in ‘trading parts’ (not talking about the parallel market with expensive used parts...)
