Balenciaga is typical of all big corporations that have a brand to protect - and want the market price under their control. Really, most companies do this in one way or another with most products.
Balenciaga is taking a path through retail that avoids many department store outlets, disallows competing sellers to be too close to each other - all standard policies for high end retailers for everything from handbags to electronic equipment.
It benefits us, because it keeps counterfeits to a minimum, Balenciaga tracks their bags, resale value remains high and Balenciaga itself doesn't have to pay as many middlemen.
BalNY clearly wants to have bags to sell to its customers - and the other outlets have to wait and see what is left over. That's how I feel anyway - the colors and styles available at Barney's BH are never particular complete.
