Registering for items you can't seem to find on a registry site!

Zola offers a custom registry where you can add random items from any site you want. I've had great luck so far with my Zola registry. I linked a couple of other registries from Amazon and Crate and Barrel and added some one-off items from sites that don't have registry options.

The Knot has a great feature through the wedding website and registry where you add a bookmark to your computer, and anytime you find something you want to add to your registry, click that button, and it connects to your registry. Pretty awesome!

I used Zola for ours and they have a google add on tool that allows you to add things from random websites to your registry, so for example I added the newly named thing and we added a specific sports thing for our custom sports bar we built in our basement, etc.

I use myregistry. It lets you link items from anywhere and you can synch other registries to it.
