Registry items N/A

I'm registered at Babies R Us and my play yard, high chair, and swing keep coming up not available! Tithe point where I went to the store to ask if they were discontinued or about to be. I was told that they are not at all about to be discontinued. It's frustrating and I worry people won't be able to get these items. And I need them! Should I switch to a different style or just hope for the best and buy them on Amazon after if they keep coming up unavailable? What would you do?
