What baby items do you regret buying because it was very seldom/never used?

Well! I do not remember any specific material utility things but I remember buying innumerable clothes for my son. We used to shop extensively for him each time we used to go anywhere. And I still remember, finding briefcases full of his unworn clothes. I even started making him wear party clothes and expensive clothes, which I bought for specific occasions at home, but if I dig inside my cupboards, there is high possibility of new clothes still lying under the heap of our clothes. May be it has something to do with the fact that I am a shopaholic. I am guilty of saying the same for myself as well. ;p
