Maybe. Authentic Choos on ebay do come around. We have gotten some smokin deals there. Just make sure you authenticate here first. That said, if you find the bag you want, in the color you want on sale at b-fly you may want to go ahead. Some here have had problems with them, tho. Not me, but several of the Choo girls have not been happy with the bags they get at b-fly. You may want to wait for the Jimmy Choo sale in late June...
The Ramona on Bluefly is the Slick Red Ramona from F/W 07. I have that bag. You can see it in the Choo Reference Library. Ramona does seem to be a classic, although is has only been out a year or two. I love the bag and the deep red color is very neutral.
Twice a year there are Choo sales. Usually the sales are scheduled around late June and early December. There are also sales in the Choo boutiques.
I am one of the gals who had big problems with BF. But you may have better luck.
