So what makes RetailMeNot’s vault.com stand out from the other coupon sites around the internet right now? Two things grabbed my attention, primarily the FireFox extension that alerts you to possible saving you could make, on purchases you are currently making. So rather than having to manually search for an adobe coupon, for example, when you visit the Adobe website, when you start to make an online order, the extension notifies you of any applicable vouchers that are available.

The other major contrast to the other copy cat sites out there is the Web 2.0 aspect of it - all offers can be reviewed by other consumers, so you know in advance if there are any catches, and just how easy other people found the relevant scheme to use.
