I'm starting to make the travel baby wipes cases and I have just a few questions... Is the only way you can get the cases are by actually buying them at Wal-Mart, Target, etc. with the wipes actually in them, then just use the cases? Do you sell them with the baby wipes in them? Do they sell well? and How much do you sell them for? Sorry for all of the questions... I'm just very new at these! Thanks so much in advance for your help!
