As long as I find the product in a good price and the shipping is reasonable and hassle-free, I have no trouble buying from around the world. Its just that usually a European has less trouble buying stuff from EU or periphery countries as shipping can be very expensive even from the UK, let alone the US or Japan.
Which takes in account both Jacco's japanese store suggestion and the generous offer of Tommy.
If Walmart or Japan Exposures can sell cheaply, I am buying.
Speaking of which, an analog mate in Athens made a very discovery:
one of the shops has a bulk of 280 cartridges of color 110, expired in 90s.
I asked my friend to test one cartridge to check the deterioration of the emulsion and the whole toy camera look and drive a hard bargain for the lot, as no matter what, the store makes a profit for a product that should have been thrown away.
