hi all, i found that some online shops sell imported fuji superia and reala films for a lower price compared to the 'usa' version of the same film. i believe they are essentially the same. but has anyone ever encounted problems with the imported films? any transportation x-ray issues when they cleared customs? also an unrelated question- when buying films online, i suppose shipping ground would be the only choice to avoid x-ray scanners they might use on air cargos? thanks!
