If my math is correct, the original discount was 25% and those remaining on sale are now 30%. There are still three medium campanas and the wheat tote that one of tPF members liked.....also some smaller sized styles.
Shirise is 100% authentic. I lived on the North Shore (the area that Glencoe is in) and it is a VERY affluent area. Shirise is a very high end boutique that only sells authentic designer bags and shoes. Look up the zip code for real estate prices/average income and you will feel more assured about authenticity.
