I am reading three sizes on the forum and for some reason I can only see two sizes at the stores on this hobo. I also can't get much info from the SA's. The BV line is not the most popular and the SA knows very little. I did meet the sweetest older woman who loves BV and has been buying them for years. We were the only two fondling them and having so much fun doing so. She said she has been buying them for 20 years and ready for her next one! Can you tell me some additional info: 1)The three sizes dimension wise and an idea of what the bag holds? 2)The costs of each? 3)The colors this bag comes in? 4)Since this bag is a classic...can it be found discounted anywhere and if yes, can I feel confident buying that it would be authentic? Thank you all for any help.
