It's definitely difficult to find a reputable place to buy Balenciaga bags.. but not impossible especially if you're like me and want to save money on a bag, but don't want to break the bank. Here are the TOP places to find a Balenciaga:
Real Deal Collection practically specializes in Balenciaga bags, and have an array of authentic bags and motorcycle jackets to suit your needs. They've recently expanded into other brands, but by far they have the most comprehensive collection of Balenciaga bags around.
HGbags is probably one of the only stores that carry both NEW and USED Balenciaga bags. She currently has the latest Balenciaga handbags in stock or available for pre-order. If you're looking for a bag that is probably not yet available in stores, or is a color that's extremely difficult to get your hands on, this is one of the best stores to find it at.
Besides these two you can typically find Balenciaga's either on Malleries, Luxury Exchange, Couture Boutique, Portero Luxury, Yoogis Closet or Anns Fabulous finds, though I found their selection quite limited... and quite frankly don't expect to find really current pieces.
If you don't mind paying regular price the following retailers also carry Balenciaga online, but expect to pay premium prices:
