Forever ago when I first started reviewing various store registries, I ended with Kohl's as one of my top picks. So we went with it and registered at Kohls. Unfortunately, we've experience a lot of difficulty with our registry their. One by one items on our registry are becoming "no longer available" and then disappearing off the registry. And they don't e-mail to keep you updated on these items either. You will only notice the items missing if you go on to their site to manage the registry. Yesterday I created a registry on Amazon.com and went through to find many of our 'missing' items on there.
Moral of the story: while Kohl's wedding registry has great perks, their inventory changes so frequently, that you need to constantly update your items and/or find some items elsewhere.
