Besides ebay, where else can I sell a BV bag? I hope I don't get in trouble for asking this - I would just like to know what my options are since I've never done this before.
Try an online consignment store, like Ann's Fabulous Finds or Yoogi's Closet. A forum search will turn up a full list. I've used both AFF and Yoogi's and have had very good experiences with both.
