ok I am so stupid but...

I'm amongst the first of my friends to get married, and I haven't really been to many family weddings, so idk what the proper 'protocol' is for A LOT of things.

Meaning: If someone is registered somewhere. I just go into the store (any location of it?) and say Hi, so and so is registered here. Can I see their registry?

Is it that simple? Help me, I am not registry savvy!

Yes! They should give you a print out and then you go look for what you want. Than make sure you tell them its from the registry so they can take it off so they don't get it twice.
You can also look online.
Hope that's what your looking for

In most big stores, yeah. But if you want to do it from the comfort of your home, then you can go to the store's website and click on 'registry'; enter the person's name and it'll pop up. Then you can view everything they registered for and decide on what to purchase for them.

Don't forget that when you are buying something in a store from someone's registry, let the cashier know! This way, it'll reflect that the purchase has been fulfilled and they (hopefully!) don't get double gifts!
