There should be enough. Besides, this is a 10 minute game - not Wyvern Tales or Zaku. (But I must admit that the poker chips are a nice addition to the game. While testing the carts I sometimes complete a Shaken, not stirred run.)
Tomorrow I should be able to test and gather some 10 copies more. But on the week-end I was invited to a sleep-over party with the theater crew from our last play and on Sunday there is Fathers day in Finland. So the shop may be open tomorrow in the evening and most likely closed for the week-end. The demand is probably fading out soon. Then I try to keep 10 copies ready to ship and leave the shop open. Just now I have exactly one copy left to ship so the shop is closed.
I just realized why I am a programmer and not a merchant.
