Basically, it's prohibited for any Medela Authorized Dealer to list pricing online. Medela only allows a few select retailers to list pricing online (like BabiesRus & Target).
In order to maintain Medela’s premium brand image, effective February 1, 2008, Medela prohibits the public listing of prices on authorized dealer websites for any or all Pump In Style and/or Freestyle Breastpump models.
Medela’s Distribution Policy applies to all Medela customers, except for a select group of Medela dealers.
Any website that is publicly listing pricing on the Internet (besides a few select retailers like Target & BabiesRus) is violating Medela's distribution policy and in turn, the product WILL NOT HAVE A VALID WARRANTY per Medela's warranty policy for products purchased from unauthorized merchants.
