I have the opportunity to buy the white caviar tote but I'm hesitating for two reasons. It will be my first Chanel purchase and maybe I need a classic flap as my first bag. Secondly, the SA says that once this bag goes they can't get any more because white isn't one of the standard colors that this bag comes in. She says that I can always get it in black or pink. Is this true about the availability of white? Also, how difficult is it to keep clean? This won't be used as an everyday bag. What do you all think?
