no for an answer

adopting a homely, but working, near-giveaway polaroid camera from a local recycling centre is all well and good, but keeping it fed - with its expensive appetite - is another matter entirely. i was delighted, it follows, to discover unsaleable.com, a nice little austrian online shop with a wealth of new and expired instant film, and accessories.
they are friendly, and fast, and charge realistic shipping fees, and i have been pleased with all my purchases, so approaching them, a few months back, with a request to sponsor the europephotobloggers' amsterdam meetup in september with a few small items, seemed a excellent idea.
at the time.
i was totally unprepared, i will admit, for the curt, condescending - indeed, sarcastic - answer that i received, and surprised by the short-sightedness of it, too. i had rather expected, perhaps naïevely, that they would astutely realise the possibilities of supporting an event involving photographers from two continents, and with a projected audience of thousands of enthusiasts.
i will still buy from them - their product is excellent, as is their service - but dismay, and disappointment, will niggle.
i'm like that.

rachel and i have bumped into a number of brick walls as far as sponsors go.
any ideas?
