Mine is five. I'm not happy with less than that, and if I had any more, I'd feel extravagant. If I sell a bag or two, I *must* replace them or I feel like I'm missing something. 5 is great for me because that's just the right number for rotating new bag styles and colors a few times a week. Does anyone else have a magic number, or is it all about racking up as many as you can?
