These are mostly from Amazon. I checked GAME, EB games, and other major stores for the lowest prices of each region. Amazon was always cheapest or equal to other stores. Some regions in which Amazon is not offered, I used major video game chains to identify the lowest price. I thought it was interesting the ranges in prices. One may expect the cost of living or the demographics of the country to have a significant impact, though, there may be more to it. Japan is understandable, the consumer's willingness to pay for pokemon is high enough for them to set a higher price. Not to mention higher income. Though, Mexico confuses me. Having been there a few times, it doesn't seem like either the willingness to pay a high price nor the ability to do so (incomes), are above most other countries. Then again, I am not that experienced with marketing, but I found the price disparities to be quite interesting.
*Prices straight from Amazon Pre-Order, I found the prices discrepancy odd between the two version in Spain.
**Price Drops on Amazon guarantees pre-orders will be charged the lowest price until the date of release. Thus, no worries about waiting since there will be reimbursement.
