You can also order Captain Disaster in: Death Has A Million Stomping Boots via long-time indie-friendly distributor BMT Micro using this link. The price is fixed at £6.99 / €7.99 / $8.99 (so depending on the exchange rate at the time it might be a better price than some other vendors).
Of course what this also means is that, if you have a BMT Micro affiliate account, you can earn 30% of any sale you make of our game. Which is worth knowing, surely? ;-)
