First of all, let me talk about the products, these Cereals are gotten from the same companies that produces the ones you buy from stores for example Nestle, Kellogg's, fun snax, royal, nasco, grand etcThese are just packed in a bigger bag in order to meet more demands, and for those that buy in large quantities like boarding schools, churches, big organization, etcExpiry dateThe same rule that applies to NAFDAC applies to this as well, same expiry date on the packed ones is same on the ones in the bigger bag. .You just have to take precautions in handling it, cos ones air incprporates in, it tends to loose taste and qualitySo it has to be properly tied and handled. On the issue of NAFDACThese products are the same with the ones you buy in stores, it carries the same NAFDAC no others carries, for example Nestle golden morn, the same NAFDAC no on the pack is the same one these ones in bigger bags carryWhat makes it cheaper is that they don't spend money on packaging the one in bigger nylonIf you buy my golden morn, you can testify to it with the ones you buy from stores
