Baby wipes question

Ka
So, this may be a stupid question but bear with me, first timer here 😊 we are about 6 mos away from welcoming our first baby and we've started buying diapers and wipes here and there to stock up. Do wipes dry out over time?? I will keep them sealed in the packaging until baby arrives but will they be okay, and still moist after 6 mos? Thanks!! 
Also, I know moms are pretty particular about diapers but I don't hear much about wipes. We've been buying all brands, esp whatever is on sale. Are any brands significantly better than others?
