These group buys have been done like this for years to cover as wide range of boards as possible; there is no way a 156 key set will cover 104, 108, TK, TKL, 60%, 75%, 40%, Preonick, Plank, ErgoDox in Dvorak, Coleman, ANSI, ISO, International,; to name just the major formats popular with the kind of people who buy 200$ keycap sets - You'd need some 300$ 200+ key monstrosity. This way, you get a lot higher number of potential buyers, which gets you more sets, which lowers your price; but these group buys will never get the numbers of the 50$ taihao market. The GMK sets do it by catering to more mainstream buyers who tend to have more commercial keyboards. Having said that, looks like this one is a bit of a record breaker, numbers wise. Judging by the questions, we are getting a lot of people new to the bespoke keycap scene.
