You may know about this site already, but in case you don't, you really should check out retailmenot.com. It's the most reliable and up to date coupon website I know about, and it covers just about every kind of commercial website, including clothing and fashion stores. What's cool about it is that each code is accompanied by a statistic telling you the percentage of folks who used the coupon successfully. That way you can easily see which codes are likely to work and which ones already out of date.
