I prefer the lottery system, although I did not win a CC, nor did I manage to get a CC in any previous sales.
Maybe due to being in Australia, we have a significant time difference to the US, plus being geographically distant means emails take those extra couple of seconds to arrive in CC's mailbox (see Hack Orange sale) which, in this case, made a significant difference.
Maybe next time don't open the draw for as long - only a couple of days to give people in all time zone a chance to enter.
And there are probably more over-priced after-draw sales this time as most people would have entered for one of everything, whether they have MX keyboard, Topre keyboard, both or neither. Sadly a noticeable number of people seem to have won CCs they did not want/need, and decided to sell them at a profit because the market is there and people are prepared to pay inflated prices.
