I have two wipe warmers; one was given to me from my sister, and another as a baby shower gift. They're cool, but they aren't needed by any means. Of course, I'm going to use mine until I run out of store-bought wipes, but my suggestion to save some money is to make your own baby wipes and ditch the warmer. They work just as good as, if not better than, the store-bought wipes, and they're super easy to make. My sister has used them on her 4 month old son since he was born, and they're awesome on his sensitive skin.
