hi ladies, a few weeks ago my passion for chanel bags was born when i was looking around in this forum. though you guys got a very detailled description and a lot of great pictures of so many bags, there are still some things i don´t understand: 1. what is the difference between a classip flap and the reissue? 2. what is the difference between caviar and lambskin? is lambskin a better quality? 3. what´s that thing with the sizes: is 226 a medium an 227 a large one? 4. what are the prizes for the classic flap and the reissues? and is it true that they are really hard to find or always sold out? sorry for bothering but it would be great if somebody could help me! thanks a lot!!!!!
