I think it depends on how you are going to use the ZC. Are using it as a clutch or wallet? As a clutch you may want to wait for a specific color. As a wallet, the color may not matter as much, so you may want to get one on sale.
I have a black one now and use it mainly as a wallet. I loooove how versatile they are. I may just stalk eBay.
Thank you for your input kiss_p and everyone!!!!
