Registry Finder makes it easy to find a wedding registry from one convenient location.
If you need to find out where a couple registered and need to do it discreetly, you normally visit each retailer's website and look for the registry section and then search for the couple's name. This takes a couple minutes for each site.
This site is a simple way to save the time you'd spend visiting each of those sites and filling out the form. Support for searching Target, Bed Bath and Beyond, Pottery Barn, Crate and Barrel, and Walmart is currently available. More stores are added each weekend, but testing is open for all.
This page and listings up to date as of 6 Sept 2008. Bed Bath and Beyond support is the latest addition.
