Judging by things for sale on corotos and friends of mine whine sell their used baby things, baby and kids clothes and products seem to sell well. Not sure I would invest my money in it though. Used clothes for babies and kids usually sell around 100 pesos per piece. It would take a whole lot of clothes to get to 500 bucks. They also don’t need a store to sell items, most sell out of their homes or use the Facebook marketplace and corotos. I’d say a salon would be a more profitable idea if the family is actually willing to do the work.
