Something I noticed about my registry

A friend of mine said she bought something off of my registry but in-store and then she went online and noticed that it never went off. Of course, she wont tell me what she bought but she says its because the salesgirl probably didn't do the purchase through the registry..just as a general purchase

Makes me wonder what else was bought that i don't know about! It makes it more fun to wonder but I noticed that all of a sudden my registry slowed down and there are still tons of people who 'apparently' haven't bought stuff yet. I know this because the gifts bought online, (the majority) get shipped to my house which is a pain in the neck! cuz my mom will have to lug all those gifts to the shower
