Short answer: everyone brings their own design
Long answer: The situation with the Alibaba chips is that the seller is a commercial seller used to dealing with larger orders. They offer price breaks at larger aggregate quantities from multiple sets per order. Moreover there are shipping efficiencies with freight shipping. So the cheapest prices on these chips occur after a group assembles orders of over 10,000 total chips. The exciting feature of these chips is that they are fully customizable. So the participants of the group buys bring their own designs or piggyback off someone else’s. Several have been made available to the public or you can hire a designer within the community. So if you find a group buy running, or run one yourself, you would design your own personal 800 chip set for example and everyone else would design theirs. Some sets are so popular, like the New China Club design, that they ran entire group buy just for people that wanted those chips. But that was more unique than the other group buys happening.
