All official dealers that distribute Segway miniPRO have to follow pricing policy set by either Segway or Segway Distribution of North America (SDONA). That is why price for official MiniPro is more or less the same among all on-line dealers (Amazon, More4Mini.com, etc) and off-line dealers (SAM'S Club, Best Buy, etc).
The easiest way to get the best price for Segway miniPRO is to get special coupons that can be applied at the checkout to lower published price. At More4Mini it is very easy to do. If you join our mailing list you will receive a discount coupon for 10% that will work for all orders over $400.00.
