Parents, do you consider buying clothes in ukay-ukay? For both you and your kids. Why or why not?

Pre-loved is okay with me. I joined online shops for moms and babies selling pre-loved items. You just have to do some checking on the background of the seller and where the clothes really came from. I don't want to buy from ukay for kids as I don't know where the clothes came from and how it was stocked. For health and hygienic purposes.
