Should I keep the packaging for all my baby items?

Abbie
So it's kind of a really morbid thought, but something I'm very wary of, just because I still can't believe I'm pregnant and can't beleive il be bringing a baby back home! But should I have kept/be keeping all the boxes for my baby items like the crib, table, baby bath ect ... I'm just worried that I'm not going to be bringing baby home yano, like I said it's a horrible morbid thought and God willing everything will be fine and il have my little baby all healthy and happy but will stores (mainly baby's r us) give money back for items that done even have its packaging? Iv already thrown out the crib and the mattress packaging! I have a small apartment and no where to store it!
