i have compared shops in Hk and USA. I found out CATHAY PHOTO singapore's prices are generally more expensive. IN addition, the prices are not fixed and not transparent.
kiwiginger, i'm splitting your posting to a new thread as it's not relevant to the topic, and to keep the momentum of the Len Price Guide going. feel free to discuss the different prices of countries here.
Could it be due to fluctuating exchange rates (HK$ is pegged at a fixed rate to US$) or the nature of how the business was conducted (store front vs online presence of some US merchants)?
