P30 was a limited run of film and sold out quickly. Advertising this film therefore would be a useless exercise.
In fact, we plan to make P30 indefinitely and, eventually, in all formats. ALPHA is the only thing that is limited and we're simply awaiting a few more tests - and some data from "the wild" - before we lift that designation.
Advertising costs money - and money, we do not have. Yes, as railwayman3 pointed out, printing 6000 postcards is super cheap. SENDING those to backers all over the world is anything but cheap - nor are we in a position to take one team member and put them on postcard duty for the two or three days it would take to properly address and stamp these hypothetical tokens of our affection...
As RattyMouse says (but in a different context) - there is no point in advertising when we can't even make enough film to meet standing demand. At this particular moment in time, putting a single cent into anything that brings MORE customers to the table would be suicidal.
We closed the shop to give the factory time to catch up because we sold about 3x more in five days than we expected to sell in 3 weeks. And that with a half-crippled shop and high shipping costs outside the EU. (side note - I've actually been called a "disgrace" for the fact that we had to cover our butts with the shipping expenses).
In fact, we've been totally heads-down and all-hands-on-deck to get the coater optimized and running full-speed, prepping emulsion, finalizing the last details of warehousing and international shipping, visiting our finishing partner to find ways for them to speed up without sacrificing quality, talking to a NEW partner about putting our own 35mm finishing line into service many months earlier than planned AND hiring two new people to help Ivano with color production. Plus fixing the shop, answering emails and comments and trying to get accurate and reliable test data from several different labs.
Looking at the incoming messaging, as I do, it also seems that we are in a situation where many people are counting our progress in Internet Time even though absolutely nothing we do happens on Internet Time. It happens on We're a Manufacturer of Physical Goods in the Real World Time and relative to Internet Time, it appears we're standing still when in fact we're racing forward at a speed that would be inconceivable to anyone who has ever made a roll of film from scratch. (That could be a tad hyperbolic, but JUST a tad...)
Like I said before, we are 100% focused on doing what we must do to get to next month and the month after that and the month after that so that everyone has something to complain about a year from now, five years from now, etc.
Progress!!
