The app is nice BUT I could not find the page with coupon codes. If its there, it is hidden. So I had to go to the Web site to shop because there was a coupon that gave me 15% off plus half off shipping. For this reason alone, the app is useless to me - I ALWAYS check the coupon page and usually there is an applicable one and to use it, you have to shop on the site. BIG screwup not to have this on the app. I will never use it.
